Fixed a few message scrolling bugs and a couple minor UI tweaks

Fixed a bug where sending a quote message could result in the messages jumping incorrectly
Fixed a bug where the quote input UI wasn't styled correctly on dark themes
Fixed a minor padding issue
Fixed an issue where in-conversation search could be a bit jumpy (simplified logic greatly)
