chore: prepare stac 1.6.0 release

[divyanshub024]

Summary

Prepares the stac 1.6.0 release and brings every package's dependencies up to date.

• Bump stac and stac_core to 1.6.0 with changelog entries (stac_core 1.6.0 is already published on pub.dev; stac will be published after this merges).
• Breaking: stac now requires Flutter >=3.44.0 / Dart ^3.12.0. The cacheExtent fix in fix: map scroll cacheExtent to Flutter 3.41 ScrollCacheExtent #493 uses ScrollCacheExtent, which first shipped in Flutter stable 3.44.0 (the fix: map scroll cacheExtent to Flutter 3.41 ScrollCacheExtent #493 message says 3.41, but the class is not present in any 3.41.x tag). cached_network_image 4.0 has the same floor.
• Update direct dependencies of all six packages to their latest versions: cached_network_image 4.0, dio 5.11, flutter_svg 2.3, json_annotation 4.12, shared_preferences 2.5.5, webview_flutter 4.14, logger 2.8, archive 4.2, build_runner 2.16, json_serializable 6.14, test 1.32, flutter_lints 6, lints 6.1. SDK floors in stac_core, stac_cli, and stac_webview are raised to match what those dependencies need.
• Refresh tracked lockfiles, generated plugin registrants, freezed/json_serializable output; format stac_webview parser.
• Use initializing formals in StacAppTheme.network to satisfy the newer prefer_initializing_formals lint.
• Add 1.5.0 (previously missing) and 1.6.0 entries to docs/changelog.mdx; raise the documented minimum SDKs in docs/quickstart.mdx.

Verification

• melos analyze: no issues
• melos build: succeeds in all four steps
• flutter test in packages/stac and stac_playground: pass
• flutter build web in stac_playground: succeeds
• dart format --set-exit-if-changed: clean
• pana . in packages/stac: 160/160 (after stac_core 1.6.0 was published)
• flutter pub publish --dry-run for stac: only the pre-existing pubspec_overrides.yaml hint

Follow-ups (not in this PR)

• Publish stac 1.6.0 after merge and tag v1.6.0.
• stac_logger, stac_framework, and stac_webview received dependency bumps but no version bump; those land on their next release.
• stac_cli has unreleased changes (Feat/dart native skills install #481) and needs its own release via the CLI release workflow.

The 1.6.0 release currently breaks external construction of network themes, so the public parameter names should be restored before merge.

- Around line 48-49: Update the public StacAppTheme.network constructor to
retain the context and request parameter names for external callers, then assign
them to the private fields in the initializer list. Keep the existing
BuildContext and StacNetworkRequest types and avoid exposing _context or
_request as named parameters.
