- Align delete section with form content
* fix: use ConfirmModal component for delete account dialog

* fix: consistent styling for delete account section
- Remove warning text (users know what delete means)
- Remove border-bottom from danger zone title (section has border-top)
- Update copilot-instructions and AGENTS.md with stricter UI consistency rules
- Remove unused deleteAccountHint i18n keys
* chore: remove pre-push test hook (CI handles tests)
Tests were running twice - in pre-push hook and GitHub CI.
Removing local pre-push tests since CI provides authoritative test results.
Use 'npm test' manually before pushing if you want local feedback.
