fix: harden geo data updates and globe refreshes

[GT-610]

Summary

• refresh globe locations when manual coordinates change and when stale self-reported addresses can be replaced by a later status poll
• validate both geo bundles and atomically replace installed data with staging, backup, rollback, and interrupted-swap recovery
• keep manifests and assets source-consistent across the primary endpoint and GitHub fallback while accepting equivalent gzip archives with different packed hashes
• remove redundant manifest checks, nested control flow, test copies, and unnecessary globe resolution scheduling found during the follow-up quality review

Context

This is a follow-up to the changes introduced by #1395 in commit fa2be93. It addresses update data loss, incomplete installation detection, cross-source manifest/asset pairing, stale manual coordinates, and expired self-reported locations.

The change does not modify the database schema, Rust or monitor protocols, public user configuration, or the external ipgeo-shards repository.

Testing

• flutter test test/server_globe_test.dart test/geo_data_revision_test.dart test/geo_bundle_test.dart test/ip_geo_test.dart (109 passed after the final main sync)
• flutter analyze lib test integration_test
• git diff --check
• flutter test (2308 passed, 30 environment-dependent tests skipped before the final main sync)

Summary by CodeRabbit

• Bug Fixes

  • Improved geo-data updates with safer installation, validation, rollback, and recovery after interrupted updates.
  • Added stronger checks for downloaded archives, including file sizes, integrity, metadata, and decompression limits.
  • Prevented incomplete or incompatible fallback data from replacing valid installed data.
  • Improved server globe updates when reported addresses or manually entered coordinates change.
  • Refreshed expired server location information more reliably.
  • Clarified download and location messages when servers cannot be placed.

• Documentation

  • Clarified that fallback archives may differ technically while containing the same logical data.

📝 Walkthrough

Walkthrough

Geo-data installation now validates complete bundles, uses endpoint-specific fetching, stages updates, and performs atomic promotion with rollback. Tests cover fallback compatibility, corrupt data, interrupted swaps, and preservation of prior installations. ServerGlobe now tracks host and manual-coordinate changes, provider updates, self-address refreshes, action widgets, and combined unplaced reasons.

Merge Risk: 🟡 Moderate · up to 23556

Globe locations may remain unplaced after a later status report supplies a mappable address, and a failed geo-data promotion may leave dependent views without a refresh signal. These correctness issues should be resolved before merge.

285-285: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Derive the staging and backup paths from the service instead of repeating the suffixes.

'${GeoData.dir}.previous' here, and '${GeoData.dir}.installing' at Lines 338 and 351, and '${GeoData.dir}.previous' at Line 352, restate the private _stagingDir and _backupDir suffixes from lib/core/service/geo_data.dart.

If a suffix changes in the service, these tests keep passing while checking paths the service no longer uses. The isFalse cleanup assertions at Lines 338, 351, and 352 would then pass without verifying cleanup.

Expose the two paths with @visibleForTesting getters, or declare them once in this file and reuse them.

In `@lib/core/service/geo_data.dart`:
- Around line 373-375: Update the failure branch of _activateStaging to
increment or otherwise change GeoData.revision after clearing the installed
state, ensuring dependent revision listeners such as ServerGlobe invalidate
their caches while preserving the existing false return.

In `@lib/view/widget/server_globe.dart`:
- Line 352: Update _fromSelfAddr and IpGeo.locate handling so a GeoMiss.noData
caused by an unmapped stored self-reported address preserves self-reported
provenance. In the unplaced-result branch, register _listenForSelfAddr for that
provenance as well as GeoMiss.private, and add a test covering a stale
self-reported address that later maps and triggers resolution.
