fix(filters): onSale chip gap + ESLint regressions from main

[adm01-debug]

Summary

Bugs found during exhaustive testing of the quick-wins implemented in #644.

• Bug fix (useFiltersPageState.ts): onSale was counted in activeFiltersCount (+1 to the badge) but had no entry in activeFiltersSummary — users could not remove the "Em Oferta" filter via the removable-chip UI. Added the missing chip entry.
• ESLint cleanup (4 files): 8 warnings introduced by main-branch commits after the ESLint baseline was generated. All suppressions are intentional patterns (test mock casts with as any, and react-hooks/exhaustive-deps where the omission is deliberate and documented).

What was exhaustively tested (and found OK)

Fix	Result
fetchProductImagesBatch — chunked IN()	✅ Map-building correct; chunks align with CHUNK_SIZE=80; deduplication works
Intl.Collator('pt-BR', { numeric, sensitivity:'base' })	✅ Verified in Node.js: Caneta 1 < Caneta 2 < Caneta 10; Abacaxi < Açaí < Água
compareNamePtBR null/undefined safety	✅ All 3 cases correct
name-asc / name-desc switch cases	✅ No longer fall through to no-op default
byNameThenId / withIdTiebreak	✅ Deterministic lexicographic id tiebreak
URL priceRange validation (NaN, negative, min>max)	✅ All edge cases handled
URL sortBy whitelist (VALID_SORT_VALUES)	✅ 11 values accepted, invalid rejected
techniquesDataAvailable guard	✅ All 3 usages (count, filter, chip) correctly gated + in dep arrays
Migration indexes — no conflict	✅ IF NOT EXISTS, different names from 20260604000003_*

Test plan

• Apply ?onSale=1 in URL on Filtros page → verify "Em Oferta" chip appears and is removable
• Verify filter count badge matches number of visible chips
• CI gates: ESLint 0 regressions, TypeScript 0 regressions

Summary by cubic

Fixes the missing on-sale removable chip and hardens filter URL parsing, while making sorting correct and stable. Also speeds up catalog queries with chunked image fetching and new partial DB indexes.

• Bug Fixes

  • Filters: add "Em Oferta" chip for onSale; validate priceRange/minStock from URL (NaN, negatives, min>max); accept only known sortBy; show/count Techniques only when product data actually has techniques.
  • Sorting: use pt-BR collator with natural numeric order; implement name-asc/name-desc; add deterministic id tiebreak across modes; align productService orderBy for name asc/desc.
  • ESLint: add targeted suppressions for intentional test casts and react-hooks/exhaustive-deps cases.

• Performance

  • Batch product images with IN(product_id) in chunks of 80 instead of fetching and filtering the full table.
  • Add partial indexes for active products on sale_price, created_at DESC, and stock_quantity DESC to accelerate catalog sorts.
