fix(android): ship stock MainActivity so the app launches (fixes crash) (1.2.11)

The manifest launches org.skatespots.app.MainActivity; when that class was
missing/wrong the app crashed on startup. Add a STOCK MainActivity (extends
BridgeActivity, no WebViewClient override) plus an idempotent injector that
guarantees it's always present after cap add / rm -rf android. This is the safe
default — the earlier custom version broke startup. Delete fix (setPackageName)
remains intact. Bump to 1.2.11.
