Step-by-step TypeScript migration with strict gates

[YaronZaki]

• Difficulty: intermediate · Effort: M · Impact: every PR
• Expected Outcome
frontend/tsconfig.json introduces strict mode in stages per directory.
  Every new .ts/.tsx file passes tsc --noEmit.
• Acceptance Criteria
  • yarn tsc finishes with zero errors per affected dir.
  • CI gate prevents merge on regression.
• Files / Modules Affected
  • frontend/tsconfig.json
• Dependencies: after docs: Fix bug_report.md issue template to support product bugs, not only CI #74.
