fix(android): cleanup and add missing resources

- Remove UDL file (using proc-macro UniFFI instead)
- Remove build.rs (not needed with setup_scaffolding!)
- Comment out zeroclaw dep temporarily (standalone build)
- Add placeholder launcher icon drawable
- Add notification icon drawable
- Fix service notification to use hardcoded strings

The UniFFI proc-macro approach is cleaner and doesn't require
separate UDL definitions - the Rust types are annotated directly.
