Note

Part of PR stack together with:

• feat: localize hardcoded strings #603 (i18n changes)

Description

This PR:

1. Adds dynamic boost fee time confirmation estimates
   • Although the UI will likely always show the same estimate as the hardcoded ones used before this implementation. This happens because fee rates values are almost always corresponding to the previously hardcoded confirmation time estimate.
2. Implements weather widget API response caching
3. Cleans up deprecated code, warnings, and TODOs across the codebase
4. Fixes all custom error types to use class instead of data class or data object
5. Adds context to logs where it was missing
6. Refactors most try/catch statements to runCatching
7. Restructures Env constants
8. Replaces deprecated MainUiState aggregate model with direct use of the separated node & wallet states exposed via wallet viewmodel
9. Simplifies lightning service by removing redundant state management
10. Removes deprecated migration test
11. Remove completed TODOs and fixes or suppresses remaining ones
12. Updates AGP & adds compose-stability-analyzer plugin
13. Clears detekt-baseline by either fixing or suppressing all lint warnings inline
14. Updates README and docs to:

• list recommended IDE plugins with setup guide
• communicates the correct paths to save the google-services.json files for each build flavor group: mainnetRelease for PROD and the STAG one for the rest

16. Captures and cancels the job handling the LDK event listener(s)
17. Fixes toast blur on wallet restore error screen
18. Refactors state for restore retry and replaces blind node start with restart in the button callback
19. Removes logs reset on wallet wipe by conditioning it only for debug builds
20. Adds reset logs to dev settings screen

QA Notes

Regression Tests:

• Test boost fee time estimates shows "±10 min" (not hardcoded but still most likely)
• Test Weather widget updates (check logs)
• Test unconfirmed transactions time estimates formatting (⚠️ refactored)
• Test receive sheet + receive → edit screen & state (⚠️ refactored underlying state)
