Maurice 01a7224f29 fix(docsync): key the Synology device token per connection and share one transport
The DSM trusted-device token was cached per NAS and account. A second trip
whose owner knew the account password but never had the authenticator could
bind the same account and log in on the first trip's token, a two-factor
bypass across trip owners. Nothing ever cleared the entry either, so a token
DSM stopped trusting went out ahead of any fresh code on every attempt until
the process restarted.

The token is now filed per connection, with instance and account still in
the key. An edit keeps the connection id, so the token survives a password
change and a stale code in the form. An unsaved form (connection 0) keeps
what its probe earns on the session only, and the saved connection adopts
it from there. A token DSM refuses with 403 or 404 is dropped for that
connection alone.

The four clients each carried their own copy of the transport, and the
copies had drifted. provider-http.ts now holds the SSRF-guarded fetch with
its timeout and certificate switch, the reading of a request that got no
answer, the base status table and the guard on a streamed download.
Timeouts, caps, auth headers and each client's error class and wording are
unchanged. Where the copies differed by accident they now agree:

- Paperless recognises UNABLE_TO_GET_ISSUER_CERT_LOCALLY (a private CA) as
  tls_untrusted instead of unreachable.
- ERR_SSL_* handshake failures read as unreachable on WebDAV too, since the
  self-signed switch cannot fix them.
- Synology maps HTTP 409, 415 and 507 like the others, Paperless maps 415.
- Every download is refused on an announced length over its ceiling and
  counted as it streams. WebDAV and Paperless had no ceiling, Synology only
  read the header, and Papra's limiter left the source pinned when it
  tripped.
- Papra reported a download without Content-Length as zero bytes, so the
  size from the listing was never used.

PapraProvider and SynologyDriveProvider are renamed PapraDocumentProvider
and SynologyDriveDocumentProvider, matching the other adapters.
