feat: IMAP Driver Integration (#12576)

### Added IMAP integration 

This PR adds support for connecting email accounts via IMAP protocol,
allowing users to sync their emails without OAuth.

#### DB Changes:
- Added customConnectionParams and connectionType fields to
ConnectedAccountWorkspaceEntity

#### UI:
- Added settings pages for creating and editing IMAP connections with
proper validation and connection testing.
- Implemented reconnection flows for handling permission issues.

#### Backend:
- Built ImapConnectionModule with corresponding resolver and service for
managing IMAP connections.
- Created MessagingIMAPDriverModule to handle IMAP client operations,
message fetching/parsing, and error handling.

#### Dependencies:
Integrated `imapflow` and `mailparser` libraries with their type
definitions to handle the IMAP protocol communication.
