Merge pull request 'Hotfix 2026.9.24.4: report reschedules keep the task queue readable' (#49) from hotfix/2026.9.24.4 into release/2026.9.24.4

Setting deliverAt on an internal DMARC or TLS report wrote the new task
queue row with the report's object type (0x21, 0x6e) instead of the task
type (7, 8), and left the task row at its old due. The task manager's scan
failed on that row with store.data-corruption ("Failed to iterate over task
queue"), and because the error ended the whole scan, every task due after
the row stopped running on every node.

- reschedule_ops writes the new queue row through schedule_task_with_id, so
  it carries the task type and the task row gets the new due. It removes
  the row the task is actually queued under (the task's due, which differs
  from deliverAt once the task has been retried) and any row an earlier
  reschedule left at deliverAt.
- x:DmarcInternalReport/set and x:TlsInternalReport/set lock the report's
  task while they move it, as x:Task/set does, refuse while the report is
  being sent, release the locks however the request ends, and wake the task
  manager.
- The task manager logs a queue row it can't read (id, due, key, value) and
  skips it instead of ending the scan. It then repairs the row from its task:
  the row is rewritten with the task's type, and a row with no task behind
  it is removed. A row holding a report's object type for a report task is
  what the old reschedule wrote: the task is moved to that row's time, as
  the reschedule intended, and its old queue row is removed. Stores that
  already hold such a row recover on their own once it comes due.
- x:Task/query with a type filter skips an unreadable row instead of
  failing.

Test: smtp::reporting::reschedule (RocksDB and PostgreSQL). It fails on
main: x:Task/get shows the old due, and with that check removed, neither
report nor a later task ever runs.

+"""Every path Cargo patches has to be in the image's build context.
+
+Cargo.toml's [patch.crates-io] can point at a directory in this repository,
+and the Dockerfile builds from a context that .dockerignore prunes to almost
+nothing. Those two facts met on 2026-09-23: a vendored, patched sieve-rs
+landed, CI stayed green -- it builds from a checkout, where the directory is
+simply there -- and the release build failed on
+
+    failed to load source for dependency `sieve-rs`
+    failed to read /build/vendor/sieve-rs/Cargo.toml
+
+after a tag had already been pushed. This is seconds, and it runs beside the
+other fork checks rather than waiting for a release to find out.
+
+Being in the context isn't enough on its own: the Dockerfile cooks the
+dependencies (`cargo chef cook`) before it copies the tree in, from a recipe
+that carries only the workspace's manifests. So each patched path must also be
+copied into that stage before the cook step, or the same error comes back
+there -- as it did for 2026.9.24.2, the first tag after the context fix.
