feat(android): add resolver import and runtime telemetry UX

[AmirrezaFarnamTaheri]

Implement the Android-only resolver import/status improvements

• add ResolverAnalyzer for Android-side resolver parsing, stats, CIDR expansion, duplicate filtering, cached import files, and cached-file cleanup
• store imported resolver metadata in ProfileEntity.advancedJson instead of adding Room columns or migrations
• normalize imported resolver files into runtime-ready client_resolvers.txt content before the untouched Go core reads them
• integrate resolver file import into Profiles and Settings, including stats cards, source badges, inline fallback, large-list safeguards, and file lifecycle cleanup on cancel/delete/replace
• make MasterDnsVpnService prefer imported resolver files, log resolver stats, fall back safely when cached files are missing, and preserve upstream profile/MTU export behavior
• track DNS scan progress, scan totals, ETA timestamps, active resolvers, synced MTU, traffic speeds, traffic totals, and connected duration in VpnManager/Home UI
• update foreground notification text with connection state, DNS scan progress, live speed, traffic totals, and active resolver count
• improve Logs UI with Android/core source tracking, filters, severity counters, share/clear actions, grouped entries, and local timestamp normalization
• preserve locked-profile import/export compatibility and include MTU export/reactive format fields during TOML import
• keep all changes limited to android/ so upstream core compatibility remains intact
