feat(cli): add pic triggers + dead-letters + secrets subcommands

Closes the audit's High-severity CLI coverage gap, raising the count
from ~25 to ~40+ subcommands and bringing the integration test count
from 63 to 73.

- pic triggers {ls, rm, create-kv, create-cron, create-dead-letter,
  create-from-json}: three per-kind wrappers cover the most common
  trigger shapes; the generic create-from-json is the escape hatch
  for docs/files/pubsub/email/queue and any future advanced retry
  knobs — body JSON inline, via @<file>, or "-" for stdin.

- pic dead-letters {ls, show, replay, resolve}: full operator
  workflow for the dispatcher's dead_letters rows, including the
  --unresolved filter and the per-row replay + manual-resolve actions.

- pic secrets {ls, set, rm}: list names + updated_at, set values
  via stdin (the only secure channel — inline values would leak
  into shell history), and delete by name. --json on set treats
  stdin as raw JSON for non-string values.

Ten new integration tests follow the established #[ignore] pattern,
gated on DATABASE_URL. All 73 ignored tests pass against the local
dev stack.

The `pic admin reset-password` server-binary subcommand exists on
the picloud binary side already; the audit's "surface it in pic
--help" note is a one-line addition deferred to Stage 6 with the
other small UX touches.
