Re-enable analyzer rules temporarily disabled for Flutter 3.47.0

[JSUYA]

To unblock the analyze CI after the stable Flutter 3.47.0 upgrade (#1088), five diagnostics newly reported by the Dart 3.13.0 analyzer were temporarily suppressed in the root analysis_options.yaml instead of modifying code. Each suppression is marked with a TODO(jsuya): Different from flutter/packages comment referencing this issue.

This issue tracks re-enabling them. Each task below removes one suppression after fixing the affected package(s) in a follow-up PR.

Tasks

1. use_super_parameters — google_maps_flutter

• Sync the example app with the upstream flutter/packages example, which already uses super.key (19 files under example/lib/), then re-enable the rule.

2. collection_methods_unrelated_type — tizen_bundle

• The two reports in example/integration_test/tizen_bundle_test.dart are false positives from intentional null-handling tests (bundle[null], bundle.remove(null)). Add // ignore: collection_methods_unrelated_type to those lines (first-party code), then re-enable the rule.

3. strict_top_level_inference — video_player_avplay, video_player_videohole

• Add the missing parameter type in both packages (void _afterFrameLayout(Duration _) in lib/video_player.dart), then re-enable the rule.

4. unintended_html_in_doc_comment — in_app_purchase

• Wrap the angle-bracketed types in backticks in two doc comments of lib/src/in_app_purchase_tizen_platform.dart (Map<Object?, Object?>? → `Map<Object?, Object?>?`), then re-enable the rule.

Deferred upstream settings (repo-wide migrations)

The following settings from the upstream flutter/packages analysis_options.yaml are also disabled with the same TODO markers. They require repo-wide migration rather than per-package fixes.

5. omit_obvious_local_variable_types — repo-wide

• Migrate the existing code, which still follows the old always_specify_types style (hundreds of violations), then enable the rule.

6. formatter: page_width: 100 — repo-wide

• Reformat the repository with a line length of 100, then enable the setting.
