Sprint: Verbeteren debug mode (#179)

* feat(PBI-49): add debugProps helper + Vitest test

Adds lib/debug.ts with debugProps(id, component, file) that returns
data-debug-id and data-debug-label attrs in dev mode, empty object in
production. Adds __tests__/lib/debug.test.ts covering both modes.

* docs(PBI-49): add debug-id pattern doc + CLAUDE.md reference

Adds docs/patterns/debug-id.md documenting the named-component boundary
rule (6 punten), helper-voorbeeld, skip-criteria en motivatie voor
handmatige pad-argumenten. Voegt verwijzing toe aan CLAUDE.md
patterns-tabel.

* refactor(PBI-49): migrate 17 shared/ components to debugProps helper
