Non modpack wireup & Project to profile install

[CodexAdrian]

Fixes MOD-376
Fixes MOD-365

[Geometrically]

• Installing anything to a existing profile doesn't seem to work (see console)
• I think the installed selection everywhere would look better if they had a checkmark next to it
• The text for the selected instance says "1.19.4 fabric", IMO "Fabric 1.19.4" would be a lot better (also should we add an indicator saying it's the selected instance?

unrelated but would be nice to fix in this pr:

• make the project sidebar like the other sidebar, where it doesn't scroll

[Geometrically]

bugs:

• going to a project's pages versions when you are adding a mod then clicking install incorrectly brings up the modal

design:

• for consistency IMO the add mods should let you click on the title/avatar to go to the profile and close the modal
• there should be an easy way to get back to search/your previous view when adding a mod and going to the page from search. maybe breadcrumbs at the top of the selector like this?

• Add Mods should be renamed to "Add Projects" or something similar
• search project type selector should be changed to a navrow
• the search headings aren't being respected

Also should add an option to create a vanilla instance

Some bugs:

• Clicking a filter when you are paginated doesn't reset the pagination (IK it's not caused by this PR but since you're working with search would be nice to fix)
• Project Type is not remembered when going back to browse
• Even when an instance is "deselected" after doing the whole add mods flow, the game versions, and other search items are not reset
• Resource Packs should be able to be installed if they are from a version before/equal to an instances (like a 1.8.9 pack should be able to be installed a 1.19 instance)
• Shader installation also doesn't seem to work
• Shader/DataPacks/ResourcePacks should ignore loaders

If I click on a mod in a profile it shows as not installed and lets me install it.

Looks good otherwise!
