silverwind 52fef74291 fix(frontend): resolve Vite assets by manifest source path (#37836)
In dev mode `/api/swagger` returned HTTP 500 (`Failed to locate local
path for managed asset URI: css/swagger.css`): the backend synthesised
asset keys from the Vite entry name instead of reading the manifest,
which only worked by coincidence and broke once a source file name
diverged from its entry name.

This keys the manifest by its source path (e.g. `web_src/js/index.ts`)
and resolves entries directly — hashed `file` in prod, dev-server source
in dev. A new `AssetCSSLinks` helper renders a JS entry's stylesheet
`<link>` tags from the manifest (the entry's CSS plus the CSS of its
statically-imported chunks).
