Fixes#7501
## Thinking Path
Issue checkout already rejects paused projects (`issues.ts` → 409), but
that fires only *after* the routine execution issue exists. Per internal
TON-1102, the pause must be honored earlier — at the scheduler tick — so
no execution issue is ever created while a project is paused. The fix
gates dispatch in `tickScheduledTriggers` on the due routine's
`projects.pausedAt`, while preserving normal cron advancement so resume
does not backfill missed firings.
## What Changed
- `server/src/services/routines.ts`:
- `tickScheduledTriggers` LEFT JOINs `projects` and derives
`projectPaused` from `projects.pausedAt`. Routines with no project are
never suppressed.
- When paused: the tick is still claimed and `routineTriggers.nextRunAt`
advances by a single cron step (catch-up backfill bypassed while paused
— no replay on resume); `recordSuppressedScheduleRun` runs instead of
`dispatchRoutineRun`.
- New `recordSuppressedScheduleRun` inserts one `routine_runs` row
(`source: schedule`, `status: skipped`, `failureReason: paused`,
`linkedIssueId: null`, `completedAt` set), updates routine/trigger
touched state, and logs a `routine.run_skipped` activity entry.
- `nextResultText` gains a `skipped_paused` branch for pause-specific
audit text (does not overload the live-issue `skipped` text).
- `server/src/__tests__/routines-service.test.ts`: focused test proving
all four acceptance criteria (no issue created while paused; one
`skipped`/`paused`/null-link run; `nextRunAt` advanced; normal resume on
a later unpaused tick).
## Verification
```bash
pnpm --filter @paperclipai/server exec tsc --noEmit
npx vitest run server/src/__tests__/routines-service.test.ts
```
- The focused test in `routines-service.test.ts` proves all four
acceptance criteria: no execution issue is created while the project is
paused; exactly one `routine_runs` row is written with `source:
schedule` / `status: skipped` / `failureReason: paused` /
`linkedIssueId: null`; the trigger's `nextRunAt` advances by a single
cron step (missed firings are not backfilled); and a later tick after
the project is unpaused dispatches normally.
## Risks
- Catch-up backfill is intentionally bypassed while paused — missed
firings are **not** replayed on resume (specified no-backfill behavior).
- Scope is deliberately narrow: manual runs, webhook/API triggers,
routine-level paused status, workspace runtime start/stop,
`concurrencyPolicy`, and `catchUpPolicy` (beyond no-backfill) are
untouched.
