v1.14.0 - Mumbai BMC handoff

Adds Greater Mumbai support and Marathi. The app now recognizes Mumbai City/Suburban districts, suggests a ward from OpenStreetMap when available, prepares compressed evidence, and opens the installed official Pothole QuickFix app (or its Play listing), BMC WhatsApp, or 1916.\n\nOpening a channel is never counted as a submission. Mumbai reports require the official BMC grievance ID before being marked submitted, and the dashboard counts only confirmed submissions. The release also adds a native Android app launcher, truthful privacy/store disclosures, and a 30-day BMC pilot/procurement pack.\n\nThis remains an independent app with no BMC affiliation or complaint API. Mumbai contract matching remains disabled until BMC supplies an authoritative road-linked award/DLP feed.\n\nThe APK preserves the existing GitHub sideload signer.
