build(ts): switch to bundler module resolution to clear TS6 deprecations

TypeScript 6 emits deprecation warnings for the prior tsconfig:

- baseUrl is deprecated and will stop working in TS 7
- moduleResolution=node10 (the implicit default) is deprecated

Switches the project to moduleResolution: "bundler" (matches how rollup
actually resolves modules) and removes baseUrl. paths still works
without baseUrl in TS 4+ as long as the entries are relative, so the
@components/* mapping now uses ./src/html/components/* explicitly.

Both deprecation warnings cleared at js-compile time.
