fix(ui): F8-08 unified number format — mono, fixed 3-decimal, no separators

Engine emits Floats at Fixed3 quantisation; UI now renders them as 3-decimal
fixed-point strings without thousand separators, monospaced via var(--font-mono)
on .numeric cells, and right-aligned in tables so columns line up on the
decimal point. Integer counts render with 0 decimals and no separators;
science fractions render as 1-decimal percent (matches the engine's third
decimal of precision).

Bug fixes from #51 (umbrella #43):
  - Player Status drive/weapons/shields/cargo: were tech LEVELS rendered
    through formatPercent (x100) — now use formatFloat (raw level).
  - Races table: same bug, same fix.

Style/UX cleanups:
  - Inspector field labels lose "stockpile" word ($ / M suffix carries it).
  - Coordinates drop the parentheses (just "x, y").
  - Inspector + report tables unify font sizes with calculator-tab
    (values 0.85rem mono, labels 0.8rem).

Files:
  - new util: ui/frontend/src/lib/util/number-format.ts
  - report/format.ts becomes a thin re-export to keep section imports compact
  - inspector planet / ship-group / actions: drop inline formatNumber,
    mark numeric <dd> with class="numeric"
  - table-races (+ bug fix), table-sciences, table-ship-classes,
    designer-science: drop inline formatters, switch to util, add
    class="numeric" on numeric <th>/<td>
  - 17 report section files: class="numeric" on numeric th/td +
    scoped CSS rule for mono+right-align
  - i18n en/ru: drop "stockpile" word, drop "%" from tech-level column
    headers in races + player_status (the "%" was the misleading bit
    from the bug)
  - tests/inspector-planet + tests/table-races: update assertions to
    match the new format

Verification: pnpm test (814 passed), pnpm check (0 errors/warnings),
pnpm build clean.
