style(admin-web): apply Prettier formatting

Run `prettier --write .` across all source files. Changes are purely
formatting: trailing commas, line wrapping at 120 chars, import
reordering, and CSS whitespace. No logic changes. Verified with
`prettier --check .` and `svelte-check` (0 errors, 0 warnings).
