feat(android-java): improve CI document seeding with inverted timestamps

- Replace simple '000_' prefix with proper inverted timestamp calculation
- Use inverted timestamp (9999999999 - current_timestamp) for reliable top positioning
- Remove unnecessary cleanup step (simpler and more reliable)
- Newer CI documents will always appear at top due to smaller inverted timestamp values
- Ensures consistent document positioning regardless of execution time
