- Add POST /mail/write/{id} sending (SendMessageUseCase, SendMessageCommand): validation, antiflood, set_mail access, ignore checks, file upload, contact creation, duplicate guard
- Add GET/POST /mail/clear/{id} (ClearConversationController, ClearConversationUseCase) with per-message soft/hard delete
- Extend MailFileService with file name parsing, extension allowlist and uploaded file storage
- Add repository methods getLastMessageBetween, updateContactTime; drop unused clearConversation
- Remove legacy /mail dispatcher route and includes/write.php
- Drop legacy compose-by-nick and base64 mini-upload paths

MailMessage and Contact relations referenced Johncms\System\Users\User (the current-user service, not an Eloquent model), causing 'Call to undefined method getConnectionName()' on eager loading. Point them to Johncms\Users\User.

- Fix route definitions: remove trailing slashes so rtrim() in index.php matches correctly
- Set legacy /mail route to priority -1 so new ContactController takes precedence on GET
- Remove MailLegacyRedirectResolver (unused in a non-public module)
