[v1.50.0] Bug fixes, QoL changes

Changes so far:

• Updated the behavior of the "go to" context button in the message inbox screen. Tapping the button to go to a comment will now load the post with just the comment chain by default, with the comment highlighted.
• Fixed a bug where tapping the add link button on the community editor will not actually insert a link.
• Changed the behavior of updating a community. The community info screen will auto-refresh if the community is updated.
• Fixed a bug where the colors used for the image viewer were wrong in light theme.
• Fixed card shadows in some places.

Update

Just realized I mistakenly titled this post "release" when it's WIP. Updated the title.
