feat: add forward option when sharing assets [WPB-26687]

[MohamadJaara]

https://wearezeta.atlassian.net/browse/WPB-26687

Adds separate “Forward in Wire” and external-share flows for logs and shared assets.

This PR builds on zipped-log sharing and extends sharing UX so users can choose whether to send content inside Wire or share it through external apps. It also hardens handling of Wire-owned FileProvider URIs, with separate behavior for Android 15/API 35+ and older Android versions.

Changes

• Add separate sharing actions for:
  • forwarding logs/files in Wire
  • sharing logs/files externally
• Add share-options bottom sheets/menu entries for log and asset sharing.
• Route Wire log sharing through ImportMediaScreen using shared file URIs.
• Introduce ImportMediaNavArgs for passing internal shared media URIs through navigation.
• Update message, conversation media, and media gallery asset sharing flows to support both Wire and external destinations.
• Keep external sharing behind the Android chooser and exclude Wire’s own share targets.
• Add Android 15/API 35+ trusted-caller handling for Wire FileProvider share intents.
• Reject public share intents containing Wire FileProvider URIs on older Android versions where trusted caller identity is unavailable.
• Restrict accepted internal Wire share URIs to the shared FileProvider root.
• Rework log archive sharing helpers so zipped logs can be shared either externally or imported back into Wire.
• Add/update tests for internal/public share URI validation, trusted vs untrusted Wire provider shares, and media sharing menu behavior.
