ProjectUpdated/Deleted, ProjectSharedWith* and TeamCreated/Deleted
carried an interface-typed Doer that could not be unmarshaled, forcing
the audit registrations to decode anonymous mirror structs. Hydrate the
doer via GetUserOrLinkShareUser at the dispatch sites like the task
events already do, register the events directly and drop the untyped
audit registration path.
Webhook payloads for these events now serialize link share doers as
their pseudo-user (negative id) instead of the raw link share object,
consistent with task events.
If both the rename and the reopen fail, logFile stayed nil while
initialized was still true, panicking on the next write. Propagate the
reopen error and retry the open on the next write so it self-heals.
Every DispatchPending caller either has the request context in scope or
is genuinely request-less, so passing it as a parameter replaces the
stored-context mechanism on the pending queue and satisfies
contextcheck. Also fixes lint findings in the audit package.
Entry schema with constructor-enforced actor/target types, a generic
RegisterEventForAudit helper that maps opted-in events to entries on
the existing watermill bus (license-gated per event since licenses are
runtime-mutable), and a JSONL writer with size-based rotation,
age-based cleanup of rotated files and batched fsync.
