feat: implement DIP/MNRL lookups and enhance Sanctions screening workflows

- Implement DIP/MNRL lookup logs table, filtering, and detail review under reports.
- Integrate DIP verification gating on client creation, allowing officers to record PROCEEDED/REJECTED decisions with reasons.
- Upgrade Sanctions verification dialog to support comparing Name, DOB, and Nationality particulars.
- Add Sanctions disposition recording (FALSE_POSITIVE / CONFIRMED_MATCH) awaiting Principal Officer approval.
- Add sanctions-alert-review-dialog for reviewers to assess and escalate/clear flagged names.
- Enforce strict screening reset logic on client name changes, preventing bypass of existing blocks.
- Update routes and shell menu navigation to include DIP/MNRL Lookups and Sanctions Logs.
