## What changed
`searchAddresses` (used by the To/Cc/Bcc autocomplete) now runs two passes over the candidate email rows:
1. **Sent-folder rows first** — the mailboxes table is queried for mailboxes with `role='sent'`; any email row whose `mailboxPath` matches gets processed before inbox/other rows. Within this group addresses are ordered by `receivedAt` DESC as before.
2. **All other rows** — processed after sent rows, also by `receivedAt` DESC.
Within sent-folder rows, `toAddresses` and `ccJson` are checked before `fromJson` (the sender in a sent email is our own address, not a useful suggestion). For non-sent rows the original order (`fromJson`, `toAddresses`, `ccJson`) is kept.
This means: if you wrote to `info@foo.de` yesterday and received spam from `info@spam.de` today, typing "i" surfaces `info@foo.de` first.
## How verified
- All 492 unit tests pass (`task test`).
- Added a dedicated test `searchAddresses prioritises sent-folder addresses over newer received` that inserts an older sent email and a newer received email matching the same query prefix and asserts the sent-folder address is returned first.
