refactor: extract duplicated code patterns into shared utilities

[devin-ai-integration]

Description

Extracts several duplicated code patterns into shared utilities/hooks:

• src/utils/useResponsiveSlider.js — shared react-slick slider lifecycle (client detection, viewport-based slidesToShow, debounced resize/load handling, optional image-load listeners, innerSlider.onWindowResized() refresh, cleanup). Adopted by:
  • src/components/Related-Posts/index.js
  • src/sections/Home/So-Special-Section/index.js
  • src/sections/Pricing/review-slider.js (keeps its .slider img load listeners via watchImagesSelector)
  • Per-component breakpoint→slides mappings are preserved unchanged via a computeSlides callback.
• src/utils/useScrollTiltEffect.js — shared scroll-driven rotateX() tilt effect previously duplicated in src/sections/FeatureHero/index.js and src/sections/SolutionHero/index.js.
• src/utils/usePaginatedSearch.js — combines the existing useDataList search with page-based slicing; replaces identical state/slicing blocks in src/pages/blog/index.js, src/templates/blog-category-list.js, and src/templates/blog-tag-list.js (same defaults: ["frontmatter", "title"], "id", 10 per page).
• src/sections/Company/Legal/legal-table.style.js — shared Sistent table styles (StyledTableContainer, StyledTableRow, StyledTableCell, StyledHeaderCell) and legalTableTheme, previously duplicated in the privacy, cookie-notice, and sub-processors pages.

Behavior is unchanged; only duplication is consolidated.

Notes for Reviewers

• The pre-commit hook (.lintstagedrc.js) needed two fixes to be able to commit at all:
  1. --no-warn-ignored added to the eslint step: eslint's "File ignored" warnings for src/utils/ files (which are in the eslint ignore list) tripped --max-warnings=0, blocking any commit touching src/utils/.
  2. Prettier now runs before eslint --fix instead of after: prettier's output violates the repo's eslint indent rules, so the previous order produced commits that fail npm run checklint (CI). With eslint last, committed files are eslint-clean.
• The hook's prettier step reformats every staged file, which accounts for the formatting-only churn in the touched files (e.g. the legal pages).
• Verified: eslint passes on all touched files; npm run build (full Gatsby build) also runs in CI.

Signed commits
