Random quality of life features

• I think I’m almost finished with MemeBoard, so now I’m just making random small features that I skipped over earlier
• Added realtime chat message previews for each of your chats that shows the last message and who sent it on the left sidebar so it feels more like Discord and Slack
• Added a tag filtering dropdown on the Memes page where you can see all the tags, search for them, and choose one to see all the memes labeled with that tag. This makes it a lot easier to browse, filter, and find similar memes
• Added an options menu button to the tag page (that only shows if you’re the one who made the tag) similar to the button I added to a bunch of other pages. When clicked, it shows a menu with just a delete option that deletes the tag and removes its label from all the memes after a confirmation modal
• Added both dynamically generated SEO and static SEO to some pages that didn’t have it
• Updated styling and navigation
