FreeTLab 163241d4a1 fix(inicio): add the favourites count badge and plain-text Ver todas
Tier 4 visual fidelity, audit 1.11/1.12 (t4 line 80): a pill badge next
to "Tus emisoras" now shows the TOTAL favorite count (not the 8-capped
grid size), and "Ver todas" is plain 12px/w800 brand-teal text instead
of a Material TextButton with its own padding and splash.

Item 1.4 (hero art radius) was already fixed as a side effect of an
earlier commit — no change needed here.
