feat(email): add Correspondence.Provider discriminator

b4 of the multi-provider email roadmap. The manual/free-text correspondence
entry path already existed (CorrespondenceController.Create) -- this slice
was narrower than the roadmap wording suggests: tag every Correspondence row
with which provider it came from (gmail | manual today; microsoft | imap
once those providers grow an import-into-Correspondence path of their own),
not build a new endpoint.

- Correspondence.Provider (nullable string), reconciled via the existing
  EnsureColumn pattern (SQLite + MySQL).
- Idempotent backfill: rows with an ExternalThreadId (historically only
  ever written by Gmail import) get 'gmail'; everything else gets 'manual'.
- GmailController.ImportSingleMessageAsync now tags Provider = "gmail".
- CorrespondenceController.Create now tags Provider = "manual".
- Both write sites use a fixed literal, not request input -- no injection
  surface introduced. Backfill SQL is static, no interpolation.

148/148 green (147 existing + 1 new CorrespondenceControllerTests; the
GmailController import test gained a Provider assertion in place).

-/// <summary>
-/// Generic IMAP mail access for "any provider not explicitly supported" (Gmail/Microsoft have
-/// their own OAuth-based providers). Auth is direct host/username/password rather than OAuth —
-/// there's no connect-url/callback dance, the caller submits credentials once and they're
-/// encrypted at rest the same way Gmail/Microsoft's refresh tokens are.
-///
-/// ponytail: scoped to INBOX only, and "thread" is approximated from the References/In-Reply-To
-/// headers (the root Message-Id) rather than the server-side IMAP THREAD extension, which not
-/// every provider implements. Good enough for "show me the other messages in this conversation";
-/// upgrade to THREAD/SORT if a target provider needs cross-folder or extension-grade threading.
-/// External message ids are "{UID}" scoped to INBOX under the connection's current UIDVALIDITY —
-/// they are not stable across a UIDVALIDITY change (rare: a full mailbox reset on the server).
