copy: rename user-facing 'UNIT' label to 'ENTRY'

[sacha-l]

Summary

"Units" read oddly, so the user-facing label for a project/entry is now ENTRY / ENTRIES. User-facing strings only — internal identifiers are intentionally untouched (no import churn).

Changes (8 files, copy only)

• Card label ENTRY {n} (unit-card.tsx) + detail modal header (unit-detail-modal.tsx).
• Home: hero stat Total Entries, directory count N ENTRIES, featured header ·NOW SHOWING / ENTRY NNN, search entries… placeholder.
• M2 program: ENTRY / TEAM column, row labels ENTRY NNN, empty state ·NO ENTRIES MATCH, search teams or entries… placeholder.
• Project detail breadcrumb ·ENTRY / ; admin card ENTRY · SUBMITTED; winners count N ENTRIES; 404 No entry found at this address.

Note: the Total Entries stat label wasn't in the original scope list — caught by the grep guard during verification and included since it's user-facing.

Not changed (internal — by design)

Filenames unit-card.tsx / unit-detail-modal.tsx; components UnitCard / UnitDetailModal; types UnitForCard / Unit; fn toUnit; field unitNumber; props unit / featuredUnit / selectedUnit. None render the word to users.

Test plan

• npm run build + npm run lint (client) — green.
• Grep guard: grep -rni unit client/src → only internal identifiers + substring false-positives ("community", "Unity SDK") remain; no user-facing UNIT/UNITS text.
• stadium-tester @ localhost (mock) — 7/7 PASS.
