Thomas Heinrichsdobler 086830f81b fix(messaging): reset sync state when IMAP/SMTP/CalDAV credentials are updated (#20405)
## Problem

Updating credentials for an existing IMAP/SMTP/CalDAV connected account
in **Settings → Accounts → Connection settings** has no effect on the
sync. The save persists the new `connectionParameters`, but
`messageChannel.syncStatus` / `messageChannel.syncStage` /
`connectedAccount.authFailedAt` are left untouched, and no fetch job is
queued.

This matters most when the channel is in
`FAILED_INSUFFICIENT_PERMISSIONS` (e.g. after Apple invalidates iCloud
app-specific passwords, or on any other auth failure):
`MessagingRelaunchFailedMessageChannelsCronJob` only retries
`FAILED_UNKNOWN`, so the account is stuck on "Sync failed" forever
despite the credentials now being correct. The only known workarounds
are a direct DB update or deleting and recreating the account.

#19273 fixed the frontend cache angle of credential editing; this PR
fixes the backend half of the same UX (the channel state machine).

## Reproduce

1. Connect an IMAP/SMTP account.
2. Force an auth failure (e.g. revoke the app-specific password
upstream). Wait until `messageChannel.syncStatus` flips to
`FAILED_INSUFFICIENT_PERMISSIONS`.
3. Generate a fresh password, edit the account in **Settings →
Accounts**, save.
4. Observe: account stays "Sync failed" indefinitely;
`core.messageChannel.syncStatus` and
`core.connectedAccount.authFailedAt` are unchanged; no IMAP connect
attempt in the worker logs.

## Root cause


`packages/twenty-server/src/modules/connected-account/services/imap-smtp-caldav-apis.service.ts
→ processAccount` saves the updated `connectionParameters` but never
resets the sync state nor enqueues a fetch job.

The OAuth providers handle this:

| Reset step | `google-apis.service.ts` | `microsoft-apis.service.ts` |
`imap-smtp-caldav-apis.service.ts` (before this PR) |
|---|---|---|---|
| `updateConnectedAccountOnReconnect` (clears `authFailedAt`) | yes |
yes | — |
| `accountsToReconnectService.removeAccountToReconnect` | yes | yes | —
|
| `resetAndMarkAsMessagesListFetchPending` | yes | yes | — |
| Enqueue `MessagingMessageListFetchJob` | yes | yes | — |
| `resetAndMarkAsCalendarEventListFetchPending` | yes | yes | — |
| Enqueue `CalendarEventListFetchJob` | yes | yes | — |

#12061 introduced this behaviour for Google/Microsoft. The IMAP service
was added later and the equivalent reconnect plumbing was never ported.

## Fix

Mirrors the Google/Microsoft pattern in `processAccount`:

- **Inside** the transaction, when an account already exists: clear
`authFailedAt` on the connected account.
- **After** the transaction, when an existing account is being updated:
  - drop the account from `accountsToReconnect` user-vars,
- if the message channel exists and IMAP is configured, call
`resetAndMarkAsMessagesListFetchPending` and enqueue
`MessagingMessageListFetchJob` (skipped while the channel is still
`PENDING_CONFIGURATION`),
  - same logic for the calendar channel and `CalendarEventListFetchJob`.

Wires `MessageChannelSyncStatusService`,
`CalendarChannelSyncStatusService`, `AccountsToReconnectService` and the
messaging/calendar queues into `IMAPAPIsModule`.

## Tests

- Extended the existing `should preserve existing channels when updating
account credentials` case to assert: `authFailedAt: null` is written
within the transaction; `removeAccountToReconnect` is called with the
resolved `userId`; `resetAndMarkAs*` and queue `add` are called for both
channels.
- New case: `should not queue fetch jobs for channels still in
PENDING_CONFIGURATION`.
- New case: `should not run reconnect logic when creating a brand new
account`.

I could not run the full server test suite locally (no `node_modules`
checked out); relying on CI.

## Out of scope

- Extending `UpdateConnectedAccountOnReconnectService` to a non-OAuth
shape: kept inline to minimise the blast radius. Refactoring opportunity
for a follow-up.
- Behaviour when the user removes IMAP or CALDAV from the parameters on
update (the channel currently lingers in its old state). Pre-existing
and not made worse by this PR.

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty deploy

See the app development guide for objects, views, agents, and logic functions.
