* feat: Add configurable retention period for temporary chats * Addressing eslint errors * Fix: failing test due to missing registration * Update: variable name and use hours instead of days for chat retention * Addressing comments * chore: fix import order in Conversation.js * chore: import order in Message.js * chore: fix import order in config.ts * chore: move common methods to packages/api to reduce potential for circular dependencies * refactor: update temp chat retention config type to Partial<TCustomConfig> * refactor: remove unused config variable from AppService and update loadCustomConfig tests with logger mock * refactor: handle model undefined edge case by moving Session model initialization inside methods --------- Co-authored-by: Rakshit Tiwari <rak1729e@gmail.com>
