Improve gallery dirs and DOM types

[bgins]

Description

This PR makes the following changes:

• [x] Refactors the directory constants eagerly create paths
• [x] Add the dom TypeScript lib
• [x] Sets noEmit to true in the tsconfig

Webnative 0.36 requires stricter path types, and our existing approach to path types required explicit types that were getting a bit complex.

Also noticed along the way that we had some type errors for window and FileList. Adding the dom lib to the TypeScript config takes care of that.

Lastly, we had an error in tsconfig.json that some JavaScript files might be overwritten. The TypeScript compiler emits files alongside source, and normally we would want to set an outDir to avoid overwriting files. But we process files with Vite, so this isn't a concern, and we can let TypeScript it won't need to emit.
