feat(enabled): scripts/routes enabled column + declarative data path

Phase-1 `enabled` three-state lifecycle (§4.3), data-model half. Triggers
already carried `enabled`; this adds it to scripts and routes and threads
it through the declarative project tool. Runtime honoring (disabled route
404 / script non-invocable / dispatcher fire-time re-check) is the next
commit — this change only stores and reconciles the flag.

- Migration 0045: `enabled BOOLEAN NOT NULL DEFAULT TRUE` on scripts +
  routes. Default true ⇒ no behavior change on migrate.
- `Script`/`Route` (shared) gain `enabled` (serde default true via the new
  `picloud_shared::default_true`); repos' SELECT/INSERT/UPDATE SQL, row
  structs, `NewScript`/`NewRoute`/`ScriptPatch` all carry it.
- Apply diff treats `enabled` as a declarative field (omitted ⇒ active):
  `script_update_reason` + `diff_routes` detect a toggle as an Update, and
  the create/update/insert paths persist it. The bound-plan `state_token`
  re-includes script/route `enabled` (removed in the earlier review fix
  precisely because the diff didn't key on it yet — now it does).
- CLI manifest model + `build_bundle` + `pull` round-trip `enabled`
  (serialized only when false; omitted ⇒ active). `pic init` scaffold and
  the interactive script/route create paths default active.

Tested: manager-core lib 365 (incl. enabled diff + token sensitivity) +
cli bins 31 (incl. manifest skip-serialize) green; clippy -D warnings
clean.
