feat: Jump to Message for Conversation Attachments

[DeveloperBlue]

This PR adds the ability to jump to messages for attachments under the conversation details pages.

It uses the existing jumpToMessage function found in MessagesService.
It is only shown for attachments opened from the conversation details pages.

• MediaGalleryCard, ConversationFullscreenHolder, and ImageDisplay now have a showJumpToMessage prop.
• Photos and Videos only ¹
• iOS: Adds a pill button with the sender's details, similar to iMessage
  Material: Adds a "See in chat" overlay button, similar to Google Messages
  Samsung: The attachment header is now tappable to trigger jumpToMessage

iOS and Material UI

iOS	Material

Links, Locations, and Other Files Not Included

¹ The other types of attachments (Links, Locations, and Other Files) all directly open their attachments externally. There are currently no places to add the jumpToMessage UI. This is the only blocker.

One solution would be a long-press context menu, similar to the "Attachment Popups" feature showcased in #2895,. This is out of scope for this PR.

Developer Notes

The current jumpToMessage method loads all the messages from the current cursor to the target message contiguously. If the target message is far away (hundreds or even thousands of messages away), this could potentially take up to minutes to load all the messages in between.
The conversation view depends on these loaded messages being contiguous, so I was not able to just load a specific window around the target message.

Aside from that, the feature works fine. If we wanted to address this, the ideal fix would be that the Messages service gets refactored to handle loading non-contiguous messages. Less ideally, there is also the way the search feature loads specific isolated message windows. This has it's own share of issues and limitations (#2269) .

Additional Fixes:

• The Fullscreen Viewer now redacts leaking contact information on the Material theme

---

Tested on an android mobile emulator and a physical android tablet

The Fullscreen Viewer does not redact contact information when using the Material theme

Any reason not to resolve this before the PR gets merged?

[DeveloperBlue]

Good point, resolved 👍

Also related: would you like me to submit the Samsung parity issues in this PR too, or just do one separate followup PR?

• Missing "Save" and "Share" buttons
• A place for the jumpToMessage button
• One more redacted mode fix for Samsung conversation headers leaking phone numbers

They're a little mixed on scope but pretty minor changes. Not sure if this adds bloat to the PR for your review. Otherwise, good to go on my end.

edit: Added UI for Samsung variant

[zlshames]

yeah, if you can, i'd like to get the feature implemented for all skins and all without leaking the name when redacted mode is enabled

[DeveloperBlue]

Added the missing media viewer buttons and fixed the redacted mode leaks for conversations with this PR 👍
