Riyadh 1de19422ad Task #303: DIN Next LT Arabic site default + working font picker
User report: "the dropdown for changing the site font does not work."
Root cause: FontSettingsSection listed Cairo / Tajawal / Noto Naskh
Arabic / Amiri, but only Tajawal had been registered with @font-face.
Picking the others was a no-op. Site default body font was also not
DIN Next LT Arabic as designed.

Changes:
- artifacts/tx-os/src/index.css: --app-font-sans now starts with
  "DIN Next LT Arabic"; dropped IBM Plex Mono.
- artifacts/tx-os/index.html: removed Google Fonts <link> + preconnect.
- artifacts/tx-os/src/pages/executive-meetings.tsx: FontSettingsSection
  dropdown replaced with the 5 actually-bundled families + system.
- artifacts/api-server/src/routes/executive-meetings.ts: FONT_FAMILIES
  Zod allowlist updated to match.
- artifacts/api-server/src/lib/sanitize.ts: FONT_NAME_PART regex now
  allows the new families (kept IBM Plex Sans Arabic for backward
  compat). Fixes a latent bug from #301 where the rich-text sanitizer
  silently stripped attendee font picks on save.
- artifacts/api-server/src/lib/pdf-renderer.ts: FAMILY_MAP and
  ARABIC_FONT_NAMES updated. Sans-style families map to the bundled
  NotoSansArabic; Naskh-style families to NotoNaskhArabic.
- artifacts/api-server/tests/executive-meetings.test.mjs: PDF
  sans-vs-naskh assertion updated from Cairo/Noto Naskh Arabic to
  DIN Next LT Arabic/Majalla, preserving its semantics. Other
  Cairo/Noto Naskh Arabic occurrences swapped to the new names.
- replit.md: documented site default font + lockstep allowlist rule.

Deviations from plan: kept DEFAULT_FONT.fontFamily = "system" on the
frontend (and the backend Zod default) instead of changing it to
"DIN Next LT Arabic". "system" semantically means "no override → use
the CSS default", which is now DIN Next LT Arabic — same end result
without forcing a migration on existing rows. The sanitizer change
was not in the original plan but was required to make the picker
actually persist.

Verification:
- Frontend tsc clean.
- Backend tsc shows the same pre-existing unrelated errors as before
  (isHighlighted boolean/number; Drizzle scope typing).
- E2E browser test verified all 7 assertions: site default font,
  no Google Fonts requests, exactly 6 dropdown options, font picker
  applies + reverts correctly, attendee font picks persist after save.
- Code review verdict: PASS.
