fix: resolve F-Droid blockers (flag Razorpay, replace Maps)

Overview

This MR resolves issues blocking the application from being accepted into F-Droid by removing proprietary dependencies and ensuring the project is fully open-source compliant and buildable.

---

What does this MR do and why?

F-Droid requires applications to avoid proprietary SDKs and be reproducible from source. The project previously included Razorpay and Google Maps, which violate these guidelines.

To address this:

• Razorpay is retained but disabled using a build-time feature flag (VITE_ENABLE_PAYMENTS) so it is excluded from F-Droid builds
• Google Maps is replaced with OpenStreetMap, an open-source alternative
• Updated "private" flag in package.json to false (can be toggled manually if needed)

Trade-off:

• Payment functionality is not available in F-Droid builds but preserved for other environments

---

Changes Made

• Updated src/pages/DonationPage.tsx to feature-flag Razorpay integration
• Replaced Google Maps iframe with OpenStreetMap in src/pages/AboutPage.tsx (updated to Swecha office location)
• Updated "private" flag in package.json to false (can be toggled manually if needed)

---

Root Cause:

• Use of proprietary services (Razorpay, Google Maps) violated F-Droid policies
