neo773 734b0bd2d2 IMAP Refactor (#14053)
- Removed `IMAPMessageLocator` service which relied on `Message-ID`
header lookups.

We now fetch messages directly by UID, which should eliminate most of
the issues we were hitting.

This had a challenge, `messageIdsToFetch` were flattened and UIDs are
only unique within their own folder.
To preserve context without modifying the core message module, I landed
on using composite keys for IMAP message IDs.

Each UID is now prefixed with its folder name, and we parse it back when
needed to recover the folder.
This feels like a reasonable trade-off since it resolves a lot of the
failures we saw with `Message-ID` lookups.

  And Syncs are faster now since there's no double scanning.

- Added `QRESYNC` support for servers that provide it, giving us faster
incremental sync.

- Refactored code to better split concerns.

Does the world need another CRM?

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
