android-test: smoke older wallet releases; blocker only if ≤14 days

Expand matrix with previous wallet-* tags (F-Droid APK or self-build). Hard-fail only for released apps younger than BLOCKER_MAX_AGE_DAYS; older releases and master remain warn-only.

-Default matrix order: `stable-self,published,master`.

+**Two-week window:** `BLOCKER_MAX_AGE_DAYS=14` (git tag age). Older apps are still tried; only young releases hard-block.
