v1.14.3

v1.14.3 — banner on any newer version, drop the patch-only suppression

_banner_recommended() only fired on minor/major bumps, on the theory
that patches are cosmetic. Today's two patches were real hotfixes —
v1.14.1 (localStorage wiping the theme/unit settings) and v1.14.2
(duplicate-card bug from MAC-blind dedup). Neither one woke the
banner on users running v1.14.0; from their dashboard's POV nothing
new ever shipped.

New rule: banner whenever the appcast's latest is greater than the
installed version, full stop. The dismiss button already stores
dismissals per-version in localStorage, so the original "users
will dismiss reflexively" concern is handled there — a user can
mute v1.14.3 specifically without losing v1.15.0 etc.

APP_VERSION bump 1.14.2 → 1.14.3, matching footer bumps.
