style(ui): system-wide UX/UI polish pass — design-system conformance + copy cleanup (#835)

* style(ui): system-wide UX/UI polish pass — design-system conformance + copy cleanup

Multi-agent scan of all 404 UI files against the locked design system, then
141 verified surgical fixes across 109 files (net -32 lines):

- Remove forbidden elevation/motion: shadow-* and rounded-xl on cards, active:scale
  bounce, hover:shadow on list items, transition-all -> transition-colors.
- Drop font-medium from single-weight Hedvig display headings/numerals.
- Replace raw rainbow Tailwind status colors with Badge variants / brand tokens /
  neutral surfaces (achromatic chrome, semantic colors stay data-only).
- Route raw dates through formatDate(), hand-rolled currency through formatCurrency(),
  add tabular-nums to financial figures; text-gray-* -> text-foreground tokens.
- Swap hand-rolled skeletons for the Skeleton primitive; off-scale spacing -> token scale.
- Fix copy: mislabeled "Leverantörsfakturor" -> "Utgifter" on bank-import outflow total,
  collapse no-op identical-branch ternaries, broken Swedish diacritics (mojibake),
  correct mismatch-password toast, correct supplier currency-field label.
- Remove PII-leaking debug console.log on register, stray console.logs.

Verified: tsc clean on all changed files, eslint clean, production build passes.

* fix(auth): sanitize residual error logs in register flow

Follow-up to PR review (compliance swarm V16 / GDPR Art.5(1)(f)): the
remaining console.error calls in the register flow passed raw error
objects, which Supabase may populate with PII (email) in nested fields.
Log only sanitized message strings instead.
