Lucas Smith 4f346d3c2d feat: add cancellable document status (#2992)
Adds a CANCELLED envelope status that privileged members (owner or team
admin/manager) can move a pending document into. Sending recipient
notifications via a background job while retaining the document in the
dashboard as proof of distribution.

Includes a dedicated Cancelled tab, single and bulk cancel actions,
the ENVELOPE_CANCELLED mutability guard, and e2e coverage for
permissions
and visibility.

/**
* Reject authoring mutations on an AES/QES envelope past DRAFT.
*
* The TSP mutation lock fires at distribution so the owner cannot replace the
* PDF between a recipient completing service-scope OAuth (against PDF_v1) and
* clicking Sign (now against PDF_v2). The SAD would authorise PDF_v2's digest
* while the recipient viewed PDF_v1 — a WYSIWYS break.
*
* SES envelopes pass through unchanged. The existing per-route guards still
* enforce COMPLETED/REJECTED rejection for them.
*
* Call this **twice** at every TSP-eligible authoring route:
*
* 1. Outside the transaction with the pre-fetched envelope snapshot —
* `assertEnvelopeMutable(envelope)` — fast-fail without a DB round-trip.
* 2. Inside the transaction with `tx` — `assertEnvelopeMutable(envelope, tx)`
* — re-fetches under the transaction's snapshot, closing the TOCTOU
* window against a concurrent `sendDocument` committing DRAFT → PENDING
* between the snapshot read and the mutation.
*
* Throws:
* - `ENVELOPE_TSP_LOCKED` when the envelope is PENDING (the case unique to
* the TSP lock — SES routes happily allow PENDING).
* - `ENVELOPE_COMPLETED` / `ENVELOPE_REJECTED` / `ENVELOPE_CANCELLED` for those
* terminal states, to stay consistent with the existing envelope-state error
* vocabulary.
