chore: fix lint issues in public.ts route file (#173)

[rajesh-puripanda]

Closes #173

Cleans up lint violations in \�pps/backend/src/routes/public.ts:

• Reordered imports according to \import-x/order\ (sibling imports then type imports, each group separated by blank line)
• Added explicit \Promise\ return type to \publicRoutes\ function
• Removed extra blank lines after imports

Verification:
\
pnpm --filter backend lint
\
→ No errors or warnings for \public.ts.

Terminal Proofs ?

1. Lint - public.ts passes cleanly

Exited with code � - no errors, no warnings.

px eslint apps/backend/src/routes/public.ts --quiet

(no output - clean pass) exit code: 0

2. Unit Tests - All 12 public.test.ts tests pass

�itest run src/tests/public.test.ts

`
? GET /api/public/:username/qr - size validation
? rejects size=0 with 400 before any DB query
? rejects size=-1 with 400 before any DB query
? rejects size=50000 (above upper bound) with 400
? rejects size=2049 (one above upper bound) with 400
? rejects non-numeric size (abc) with 400
? rejects floating-point size (400.5) with 400
? accepts size=1 (lower bound) and returns PNG
? accepts size=2048 (upper bound) and returns PNG
? defaults to size=400 when no size param is provided
? returns SVG when format=svg is requested
? returns 404 for an unknown username (valid size)
? returns 500 when QR generation throws

Test Files 1 passed (1)
Tests 12 passed (12)
`

3. Full test suite (100 passed / 7 pre-existing failures)

The 7 failures are pre-existing in event.test.ts and �pp.test.ts (env-related - process.exit due to missing JWT_SECRET/ENCRYPTION_KEY in test env, and an unrelated attendees pagination issue). They are not caused by this PR's changes, which are scoped to public.ts only.

Ready for merge! ??

Update: Typecheck & Lint Issues Resolved

Typecheck: All 15 TypeScript errors are fixed. Root cause was a missing \prisma generate\ - after generating the Prisma client, \TeamRole, \PrismaClientKnownRequestError, and all implicit \�ny\ parameters are now properly resolved. \ sc --noEmit\ passes with 0 errors.

Lint: \src/routes/public.ts\ passes with 0 errors, 0 warnings (scope of this PR).

Merge conflicts: Resolved - branch merged with latest \upstream/main.

Files verified clean:

• \�pps/backend/src/routes/public.ts\ ? lint & typecheck pass
• \�pps/backend/src/utils/error.util.ts\ ? typecheck pass
• \�pps/backend/src/routes/team.ts\ ? typecheck pass
• \�pps/backend/src/services/publicService.ts\ ? typecheck pass
• \�pps/backend/src/tests/team.test.ts\ ? typecheck pass

Ready for review and merge. Marking as critical since the typecheck failure was blocking CI.
