feat(v1.1.1-triggers): triggers + outbox schema + repos

Migrations 0008-0011 lay down the triggers framework's storage:

- `triggers` + `kv_trigger_details` + `dead_letter_trigger_details`
  (Layout E, design notes §2). Parent table carries common columns
  including `registered_by_principal` — the dispatcher uses this to
  run the trigger as the user that registered it (design notes §4).
- `outbox`: universal async dispatch substrate. KV/cron/pubsub/queue/
  email/dead-letter all write rows in the same shape; the dispatcher
  claims due rows via FOR UPDATE SKIP LOCKED. `reply_to` is the
  NATS-style inbox id for sync HTTP (commit 6) — its presence flags
  "don't retry" per the design.
- `dead_letters`: exact schema from design notes §4 with the four-
  value `resolution` CHECK constraint (`replayed | ignored |
  handled_by_script | handler_failed`) and partial index on
  unresolved rows for the dashboard badge.
- `abandoned_executions`: forensic table for the dispatcher's
  "tried to resolve a dropped inbox" edge case (design notes §3 #9).

Repo surfaces with Postgres impls behind traits so unit tests can
swap in-memory backings:
- `TriggerRepo` — CRUD + the `list_matching_kv` /
  `list_matching_dead_letter` hot paths the dispatcher uses.
  Includes a `collection_matches` helper that handles `*`, `prefix:*`,
  and exact-name globs.
- `OutboxRepo` — insert + claim-due + delete + reschedule.
- `DeadLetterRepo` — insert + get + list + unresolved-count +
  resolve + GC.
- `AbandonedRepo` — insert + GC.

`TriggerConfig::from_env` (new module) follows the existing
`SandboxCeiling` env-loading pattern for `PICLOUD_MAX_TRIGGER_DEPTH`,
`PICLOUD_TRIGGER_RETRY_*`, `PICLOUD_DEAD_LETTER_RETENTION_DAYS`, and
`PICLOUD_ABANDONED_EXECUTIONS_RETENTION_DAYS`.

`Capability::AppManageTriggers(AppId)` and `AppDeadLetterManage(AppId)`
join the enum. Both map onto the existing `Scope::AppAdmin` per the
seven-scope commitment; `role_satisfies` grants them at the
`AppAdmin` per-app role.
