feat(ui): full e-ink refresh on screen change + prune gone favourites

Browse Source 
Two UI quick wins from the 2026-07-05 review:

- E-ink: force a full (non-partial) refresh on the first frame of a new
  screen. Inter-screen ghosting was the most visible cheap win — the
  N-partials interval alone doesn't catch navigation. New
  DisplayDriver::forceFullRefresh() (no-op on OLED), set in setCurrScreen()
  and consumed by GxEPDDisplay::endFrame().

- Favourites: clear a stale "(gone)" tile at render time so it reverts to an
  empty "+" slot. Happens when prefs outlive the contact list (e.g. a wiped
  /contacts3); onContactRemoved only catches a live delete. Pruned slots are
  persisted once per pass (self-healing — an emptied slot can't re-fire).

Builds green: WioTrackerL1_companion_solo_dual (OLED),
WioTrackerL1Eink_companion_solo_dual (e-ink).
