nav_mini: false — opt a single element out of nav.live: full's mini thumbnail

nav.live: full shows a room's whole live state in its own thumbnail — gauges, labels, icons,
badges, blinds, embedded cards, everything, unconditionally. That's the point of full, but it
also means one specific element (a cluster of "open section" launcher icons, say) can end up
cramped or cluttered at thumbnail scale with no way to hide just that one thing short of switching
the whole room to custom and re-opting everything else back in.

nav_mini is now honored in both live tiers, with opposite defaults matching each tier's own
starting point: custom stays opt-in (nav_mini: true to show an otherwise-hidden element),
while full is now opt-out (nav_mini: false to hide an otherwise-shown one). The editor's
per-element "Show in mini" checkbox becomes "Hide from mini" once live: full is active — same
field, same checkbox, meaning flipped to match the tier. Purely additive: an existing full config
with no nav_mini fields renders identically to before.
