Refactor docker-compose.yml for consistency and add new services; update librechat.yaml with additional model references and configuration adjustments.

- Introduced `inferMimeType` utility to improve MIME type detection for uploaded files, including support for HEIC and HEIF formats.
- Updated DragDropModal to utilize the new inference logic for validating file types, ensuring compatibility with various document upload providers.
- Added comprehensive tests for `inferMimeType` to cover various scenarios, including handling of unknown extensions and preserving browser-provided types.

-      '\n' +
-      'One sunny day, while exploring the outskirts of the village, Ethan stumbled upon an old dusty book hidden amongst the roots of a majestic ancient oak tree. It was a book of fairy tales, filled with vivid descriptions of enchanted forests, magical creatures, and extraordinary adventures. Intrigued, Ethan opened the book and began reading.\n' +

-      '\n' +
-      'Together, they stumbled upon a shimmering lake that seemed to glow with an otherworldly light. At the center of the lake, resting atop a small island, was a humble cottage made of petals and leaves. It belonged to an ancient and wise sorceress named Celestia.\n' +

As the golden sun bathed the bucolic land in its effulgent light, he would tread through the village, his ears attuned to the tales spun by the townsfolk, his eyes absorbing the tapestry woven by the world surrounding him.\n' +

The dust gathered upon it spoke of time\'s relentless march. A book of fairy tales – garnished with vivid descriptions of mystical woods, fantastical beasts, and ventures daring beyond the ordinary humdrum existence. Intrigued and beguiled, Ethan pried open the weathered pages and succumbed to their beckoning whispers.\n' +

-      '\n' +
-      'Thus, he bade tearful farewells, girding himself for a path that guided him to a dense and captivating woodland, whispered of as a sanctuary to mythical beings and clandestine troves of treasures. As Ethan plunged deeper into the heart of the arboreal labyrinth, he felt a palpable surge of electricity, as though the sylvan sentinels whispered enigmatic secrets that only the perceptive ear could discern.\n' +
-      '\n' +
-      'It wasn\'t long before his path intertwined with that of a capricious sprite christened Sparkle, bearing an impish grin and eyes sparkling with mischief.

-      '\n' +
-      'Celestia, with her power to bestow a single wish on any intrepid soul who happened upon her abode, met Ethan\'s desire with a congenial nod, his fervor for a grand expedition not lost on her penetrating gaze. In response, she bequeathed unto him a necklace of magical manufacture – adorned with the rare gemstone known as the Eye of Imagination – whose very essence transformed dreams into vivid reality. From that moment forward, not a single cogitation nor nebulous fanciful notion of Ethan\'s ever lacked physicality.\n' +

-      'Energized by this newfound potency, Ethan continued his sojourn, encountering mythical creatures, unraveling cerebral enigmas, and braving perils aplenty along the winding roads of destiny. Armed with the Eye of Imagination, he brought forth life from immobile statuary, unlocked forbidding portals, and even tamed the ferocious beasts of yore – their fiery breath reduced to a whisper.\n' +
-      '\n' +
-      'As the weeks metamorphosed into months, Ethan grew wiser and more attuned to the ebb and flow of the world enveloping him. He gleaned that true adventure isn\'t solely confined to sating a thirst for adrenaline and conquering the unknown; indeed, it resides in fostering compassion, fostering amicable bonds, and cherishing the beauty entwined within the quotidian veld.\n' +
-      '\n' +
-      'Eventually, Ethan\'s quest drew him homeward, back to his village. Buoying the Eye of Imagination\'s ethereal power, he imbued the hitherto unremarkable settlement with the patina of infinite possibilities.

He navigated the barren plains, where the sun beat down, merciless and unrelenting, scorching the parched earth beneath his weary boots.\n' +
-      '\n' +
-      'Desolation was his only companion, the forsaken landscape a testament to the darkness that had befallen this forsaken realm. The wind whispered secrets long lost, carrying with it the echoes of a civilization long since undone, swallowed by the abyss.\n' +
-      '\n' +
-      'Amongst the shattered remnants of fallen cities, he sought solace, a glimmer of hope amidst the desolation. Rusted remnants of steel and concrete stood as sentinels of mankind\'s hubris, their jagged edges a chilling reminder of the fragility of all that was once deemed invincible.\n' +
-      '\n' +
-      'As twilight descended, casting a pallid hue upon the lifeless land, he happened upon a dilapidated house, its walls crumbling under the weight of time. Drawn to the desolation, he pushed open the creaking door, its rusty hinges screaming in protest.\n' +
-      '\n' +
-      'Inside, a world frozen in time awaited him. Dust particles danced through the air, illuminated by slivers of light that pierced the broken windows. Here, the past lay trapped, a melancholic tableau of lives lost and dreams shattered.\n' +
-      '\n' +
-      'He wandered through the empty rooms, bare walls whispering stories untold. In the corner, a dilapidated piano stood, its ivory keys long since abandoned by a musician\'s touch. He approached it cautiously, a faint glimmer of anticipation igniting in his weather-worn eyes.\n' +
-      '\n' +
-      'Determined, he carefully brushed away the dust and debris that cloaked the instrument. With trembling hands, he pressed a key, and a discordant note filled the air, mingling with the sighs of forgotten melodies. The sound echoed through the silence, bringing with it the remnants of forgotten symphonies.\n' +
-      '\n' +
-      'In that abandoned house, amidst the debris of shattered dreams, he found solace in the music of despair. With each stroke of his fingers, he conjured haunting melodies, melodies that transcended the desolation and spoke of a longing for redemption and rebirth.\n' +
-      '\n' +
-      'The notes carried his sorrow, his hopes, and his regrets, reaching far beyond the confines of that forsaken house. They traversed the desolate plains, resonating through the ravaged land with an eerie grace, enwrapping all who roamed there in a melancholic embrace.\n' +
-      '\n' +
-      'As the last notes faded, swallowed by the unforgiving stillness, he left the house behind, forever etching his presence upon its crumbling walls. The music remained, reverberating through the wasteland, a reminder that even amidst the devastation, beauty could be found, and a glimmer of hope could arise from the deepest darkness.\n' +
-      '\n' +
-      'And so, the lone traveler continued his journey, traversing the desolate expanse, his heart burdened with the weight of the world. In the face of utter desolation, he found solace in the haunting melodies, his music becoming a testament to the resilience of the human spirit, a testament to the undying flame of hope that flickered within us all.\n' +
