🏗️ refactor: Extract DB layers to data-schemas for shared use (#7650)

* refactor: move model definitions and database-related methods to packages/data-schemas

* ci: update tests due to new DB structure

fix: disable mocking `librechat-data-provider`

feat: Add schema exports to data-schemas package

- Introduced a new schema module that exports various schemas including action, agent, and user schemas.
- Updated index.ts to include the new schema exports for better modularity and organization.

ci: fix appleStrategy tests

fix: Agent.spec.js

ci: refactor handleTools tests to use MongoMemoryServer for in-memory database

fix: getLogStores imports

ci: update banViolation tests to use MongoMemoryServer and improve session mocking

test: refactor samlStrategy tests to improve mock configurations and user handling

ci: fix crypto mock in handleText tests for improved accuracy

ci: refactor spendTokens tests to improve model imports and setup

ci: refactor Message model tests to use MongoMemoryServer and improve database interactions

* refactor: streamline IMessage interface and move feedback properties to types/message.ts

* refactor: use exported initializeRoles from `data-schemas`, remove api workspace version (this serves as an example of future migrations that still need to happen)

* refactor: update model imports to use destructuring from `~/db/models` for consistency and clarity

* refactor: remove unused mongoose imports from model files for cleaner code

* refactor: remove unused mongoose imports from Share, Prompt, and Transaction model files for cleaner code

* refactor: remove unused import in Transaction model for cleaner code

* ci: update deploy workflow to reference new Docker Dev Branch Images Build and add new workflow for building Docker images on dev branch

* chore: cleanup imports
