fix(web): booth UI/UX pass — readable font scaling + booth layout/report clarity

A round of operator-facing fixes on the booth screen, shift views, and the
font-scale control. (Follows the font-scale feature in f706726, which used CSS
`zoom` — reverted here for the rem approach below.)

Font scaling (the A−/A+ control now actually works without breaking layout):
- The control scaled via CSS `zoom`, which also scaled viewport-locked containers
  (h-screen frame, max-h-[90vh] modals) so at 130% modal headers/footers were
  pushed off-screen. Reworked to scale TEXT only: converted every `text-[Npx]`
  font utility to rem across the web app (~230 sites in 25 files + the
  .label/.hint/.btn component classes + body in index.css; 16px root, so 100% is
  visually identical), and applyFontScale now sets the ROOT font-size. vh/h-screen
  layout stays put, so chrome never clips; tall content scrolls its own container.
  Verified at 130%: text 12px→15.6px while the frame stayed viewport-height.

Live feed (event rows):
- Plate, badges and reason now flow inline after the identity and wrap only when
  the row runs out of width — no more forced second line when there's empty space.
- Dropped the redundant TARGË via-badge (the plate chip already conveys it).
- Removed the Direction filter group (Hyrje/Dalje) — it duplicated the entry/exit
  options already in the Type filter.

Active sessions:
- Rebuilt as a real table (Ticket/subscriber · Plate · Entry · Elapsed) so columns
  align and long values (subscriber names, ticket ids) no longer truncate.
- Dropped the status column (an unpaid transient is normal; a subscriber shows ★ +
  name; overstay keeps a row tint). Removed the now-redundant status filter; only
  the Transient/Subscriber filter remains. Plate is now searchable (uses s.plate).

Shift report (close-shift modal + Shift History + printed Z-report slip):
- Removed the confusing `shitje` (subscription-sales) sub-line — Abonime is the
  total; only the out-of-window part is broken out. subscriptionSalesMinor stays in
  the signed payload (audit data), just not displayed/printed.
- Show the inherited opening cash ("Arka fillestare") above the expected drawer, so
  opening + cash-taken = expected reads clearly. Money values no longer line-wrap.

Subscription edit modal:
- Fixed the 2-col grid alignment: a lone "only one version" cell was shifting every
  following row by one column — it now emits a full label+value pair.

Removed orphaned i18n keys (fStatus*, fDir*, srcSubSales) from sq+en (parity kept).
Full workspace build/lint/test green.
