chore: fix all warnings and code cleanup

[ovitrif]

This PR:

1. Localizes most of the remaining hardcoded strings
   • Some toast messages aren't yet localized but the plan is to refactor the toast apis so we can pass either resourceId or string and localize the remaining texts in the PR for that work.
2. Adds dynamic boost fee time confirmation estimates
   • Although on UI it will almost always still show the same estimate as the hardcoded one, that is because of the values of the fee rates.
3. Implements weather widget API response caching
4. Fixes WalletRepo state management by replacing uiState with individual repo states
5. Cleans up deprecated code, warnings, and TODOs across the codebase
6. Fixes all errors to use class instead of data class or data object
7. Adds context to logs where it was missing
8. Refactors most try/catch statements to runCatching
9. Restructures Env constants
10. Replaces combined main uiState with direct use of the separated node & wallet state
11. Simplifies LightningService by removing redundant state management
12. Removes deprecated migration test
13. Remove completed TODOs and fixes or suppresses remaining ones
14. Updates AGP & adds compose-stability-analyzer plugin
15. Fixes or suppress all lint warnings
16. Updates README and documentation adding recommended IDE plugins with setup guide
17. Localizes articles timestamps using modern android APIs for relative time texts
18. Captures and cancels job for LDK event listener
19. Fixes toast blur on wallet restore error screen
20. Removes logs reset on wallet wipe (now only for debug builds)

QA Notes

Tests:

1. Boost Fee Estimates

• Open a pending on-chain transaction
• Tap boost/accelerate
• Verify fee slider shows dynamic time estimates (e.g., "~10 min", "~30 min")

3. Weather Widget

• Enable weather widget
• Observe API calls are cached (check logs)
• Widget should still update but without excessive network requests

4. Regression Testing

• Verify wallet balance displays correctly
• Test sending and receiving Lightning payments
• Confirm background notifications work as expected

5️⃣ - Check timestamps of articles in widget using different languages - should be localized

@claude what are the steps of the failing e2e tests and which tests are specifically failing, so we can test manually and fix the implementation on this PR as needed
