Bun, Inferno->React migration (#22529)

Re-creation of https://github.com/Aurorastation/Aurora.3/pull/21046 to
skip merge conflict hell. Brings us modern TGUI.

**ALTERNATE TITLE: TGUI HELLSCAPE PR
ABANDON ALL HOPE YE WHO ENTER HERE**

- [x] Migrate build tools (javascript -> typescript, bun for package
management).
- [x] Upgrade all TGUI dependencies and associated root files to
TG-congruent versions (axios, babel, dompurify, eslint, highlight,
marked, prettier, sass, source-map, stacktrace-parser, typescript).
- [x] InfernoJS -> React migrations
- [x] React cleanup and polish (migrate all remaining .js files to
appropriate .ts or .tsx filetype, all remaining hooks, linting, error
corrections, etc.)
- [ ] Test all remaining TGUI interfaces
