🔧 fix: Add support for configurable MongoDB database name in connection logic

* chore: Update import for isEnabled utility in convoAccess middleware

* refactor: Migrate Share functionality to new methods structure in `@librechat/data-schemas`

- Deleted the old Share.js model and moved its functionality to a new share.ts file within the data-schemas package.
- Updated imports across the codebase to reflect the new structure.
- Enhanced error handling and logging in shared link operations.
- Introduced TypeScript types for shared links and related operations to improve type safety and maintainability.

* chore: Update promptGroupSchema validation with typing

* fix: error handling and logging in createSharedLink

* fix: don't allow empty shared link or shared link without messages

* ci: add tests for shared link methods

* chore: Bump version of @librechat/data-schemas to 0.0.9 in package.json and package-lock.json

* chore: Add nanoid as peer dependency

- Introduced `nanoid` as a dependency in `package.json` and `package-lock.json`.
- Replaced UUID generation with `nanoid` for creating unique conversation and message IDs in share methods tests.
