Implemented full support for JMAP shared folders (delegated mailboxes):
Core Features:

- Virtual "Shared Folders" parent with account grouping in sidebar

Technical Implementation:
- Store all accounts from JMAP session (primary + shared)
- Transform mailbox IDs: primary uses original, shared use "accountId:mailboxId" format
- Store originalId for JMAP queries while using namespaced IDs in UI
- Transform email mailboxIds to match namespaced mailbox IDs for proper counter updates
- Pass accountId parameter through entire operation chain (fetch, view, mark read)
