When authenticating with a local-part username (e.g. 'user' instead of
'user@domain.tld') on Stalwart 0.15.x, the default sender could resolve
to an alias identity instead of the canonical mailbox address.
- Add emailMatchesUsername() helper that matches local-part usernames
against full email addresses (e.g. 'user' matches 'user@domain.tld')
- Prefer canonical identities (mayDelete=false) over aliases as tiebreaker
- Add preferredPrimaryId to identity store (persisted to localStorage)
so users can explicitly set their default sender
- Add 'Set as Primary' star button in identity manager modal
- Fix sendEmail() fallback identity resolution for local-part usernames
- Add i18n strings for all 8 supported locales
Fixes#43
- Add syncIdentities() to auth store to propagate identity changes from
identity store, fixing stale data that caused save failures and duplicates
- Call syncIdentities() after every create, update, and delete in the
identity manager modal
- Switch email composer to read identities from identity store for
consistency with the rest of the app
- Append identity text signature (with RFC 3676 separator) to email body
when sending from the composer and quick reply paths
- Add tests for syncIdentities and signature appending logic

and double-click to reset to default width

Email Multi-Selection & Drag-and-Drop
- Ctrl+Click (toggle) and Shift+Click (range) on all list items
- Add selectRangeEmails and lastSelectedEmailId to email-store
- Enable drag-and-drop on thread items and thread headers
- useEmailDrag accepts optional threadEmails for full-thread drag
