revert(eink): drop full refresh on screen change — too much black-flash

A full (non-partial) refresh on every screen change (638eea7b) turned out to be
far too aggressive on real e-ink hardware: every navigation black-flashes,
which is worse than the ghosting it was clearing. Remove the whole mechanism —
DisplayDriver::forceFullRefresh() virtual, GxEPDDisplay's _force_full flag and
override, the endFrame() branch, and the setCurrScreen() call. E-ink is back to
interval-only full refreshes (Settings > Full refresh interval).

The favourites "(gone)"-tile prune that shipped in the same commit is kept.

Builds green: WioTrackerL1Eink_companion_solo_dual.

### Under the hood
- **OLED draws less** — the SH1106 driver now skips pushing a frame over I²C when it's byte-identical to the last one, cutting redundant traffic and a little power on the static screens (clock, home) that don't change between updates.
- **e-ink: cleaner screen changes** — switching screens now forces a full (non-partial) refresh on the first frame of the new screen, clearing leftover ghosting from the previous screen that the periodic partial-refresh interval didn't catch.
