Description

Remove customWidgets folder

The last custom widget (calendar-custom-web) has been removed, so this cleans up the now-empty packages/customWidgets/ folder and all remaining references to it.

Changes

• Remove calendar-custom-web widget and the customWidgets/ folder
• Drop the obsolete react-big-calendar@0.19.2 patch (only used by the deleted widget; calendar-web uses ^1.19.4 and is unaffected)
• Remove customWidgets references from copilot-instructions.md, Renovate ignorePaths, and the update-screenshots CATEGORY_DIRS

No functional impact — workspace globs (packages//) self-adjust and pnpm-lock.yaml was regenerated.

Findings

⚠️ Low — Placeholder JIRA ticket number in PR title

File: PR title
Note: The title contains [WC-xxxx] which looks like an unfilled placeholder. Either replace it with a real ticket number, or drop the JIRA prefix and rely on the conventional-commit chore: prefix alone (both formats are accepted per repo conventions).

⚠️ Low — Snyk security check shows 3 failures

File: CI checks — security/snyk (AppDev AppStore content)
Note: The check reports "3 tests have failed". Since this PR only deletes code, it cannot introduce new vulnerabilities — these failures are very likely pre-existing across other packages. Confirm with the team that these Snyk findings are known/pre-existing and not newly surfaced by the dependency graph change (removing react-big-calendar@0.19.2 and its transitive deps could theoretically surface a previously-suppressed finding). No action required if pre-existing.

Positives

• Complete cleanup confirmed: a repo-wide grep finds zero remaining customWidgets references after the change.
• The react-big-calendar@0.19.2 patch and all its orphaned transitive dependencies (dnd-core, redux@3.7.2/@4.2.1, react-dnd, react-overlays@0.7.4, warning@2.x/3.x, symbol-observable, etc.) are cleanly removed from the lockfile — good dependency hygiene.
• Removing the ignorePaths from Renovate means the remaining packages will now properly receive automated dependency updates — a correct and forward-looking cleanup.
• The CATEGORY_DIRS set in the screenshot automation script is trimmed precisely, with no over-removal.
