v1.2.2 — HTTPS endpoint parsing fix

Fixed

• Accept full http:// and https:// LM Studio endpoint URLs, including optional ports and base paths.
• Preserve legacy hostname + port profiles.
• Resolve HTTPS defaults correctly (443) and prevent scheme-as-host / double-scheme URLs.
• Preserve the v1.2.1 APK signing certificate for in-place updates.

Verification

• 20 unit-test executions passed (10 debug + 10 release).
• Clean Gradle test lint assembleRelease assembleDebug passed.
• Release APK verified with aapt, zipalign, and apksigner.
