## Summary
The `twenty-app-dev` Docker image previously passed `--dev-mode` to
`cron:register:all`, which skipped all calendar, messaging, and workflow
sync cron jobs (only 4 generic crons were registered). This caused
periodic sync to silently stop after the initial import for community
members using the dev image as their actual instance.
## What changed
- Removed `--dev-mode` flag from
`packages/twenty-docker/twenty-app-dev/rootfs/etc/s6-overlay/scripts/register-crons.sh`
so the dev image registers all cron jobs (matching production behavior)
- Removed the now-unused `--dev-mode` option, `DEV_MODE_COMMANDS` set,
and conditional filtering logic from `cron-register-all.command.ts`
## Why this is safe
- **No log noise**: cron jobs gracefully no-op when no connected
accounts exist — they query for pending channels, find zero, and exit
early
- **No false banner**: the "reconnect account" banner only shows when a
user explicitly connected an account whose OAuth later fails, which is
correct behavior. No seed/demo data creates connected accounts, so a
fresh dev instance won't see any banner
- **Hiding crons just hid the symptom**: silently breaking sync with no
user feedback is worse than showing the banner if OAuth is misconfigured
## Context
Surfaced by a community member who reported that calendar sync cron jobs
never appeared in the queue after restarting the dev image, and only the
initial import worked. `--dev-mode` was added in #19138 as an
optimization for development but it doesn't match how the dev image is
actually used by community members deploying Twenty.
## Test plan
- [ ] Build/run the `twenty-app-dev` image
- [ ] Confirm worker logs show all cron jobs registering (calendar,
messaging, workflow, etc.)
- [ ] With no connected accounts: confirm no errors or log noise
- [ ] With a connected Google calendar: confirm periodic sync triggers
after ~5 minutes
