Polish sprint 2/2: layouts, UX consistency, pf2e conditions

Layout:
- CombatantRow: action controls (damage/AC/move/remove) grouped into one
  right-aligned wrapper so they wrap together instead of scattering on narrow
  widths.
- top bar: the campaign switcher now shrinks/truncates instead of overflowing
  on tablet widths.
- character sheet header: stat coins go full-width grid on mobile; the name
  truncates and scales down on small screens.

UX consistency:
- player Cast and resource Spend/Regain no longer fail silently — Cast shows the
  reason, resource −/+ disable at their bounds.
- the AI encounter builder now catches load failures and reports them; level-up
  advisor shows the human error message, not the error-kind enum.
- section headers standardized on the .smallcaps design token across 16 files
  (replacing an ad-hoc uppercase class).
- player HP bar uses the shared Meter primitive.

pf2e depth: condition-effects table gains drained, dazzled, enfeebled, fatigued.
FeatCard: dropped a dead text-xl wrapper left from the emoji purge.

Left as documented (functional, off-theme, refactor-risky): the native
confirm/prompt in Settings cloud-conflict and the session-password flow.

Gate: 293 unit + 35 e2e + 2 realtime; tsc + build clean.
