Wire status formatters / badges on the type:index manifest pages

[rubenvdlinde]

Context

softwarecatalog is on the Tier-4 CnAppRoot shell with @conduction/nextcloud-vue@^1.0.0-beta.40 (these landed in #226), so its six type:"index" pages (Contactpersonen, Contracten, Standaarden, Reviews, Komplianties, Moduleversies) now self-fetch and render rows. The column values are raw — no formatter / widget / aggregate wired yet.

Ask

1. Add src/services/formatters.js (procest is the reference) and pass it as :formatters to CnAppRoot in App.vue. Prefer widget:"badge" (built in) for status columns.
2. Wire status/enum columns:
   • Contracten — status column → widget:"badge"
   • Standaarden — status (and categorie?) → widget:"badge" / formatter
   • Komplianties (compliance) — its status field → widget:"badge"
   • any date columns → formatter (or wait for the built-in date formatter — nextcloud-vue#224)
3. Consider an aggregate column where useful — e.g. a Standaard's "N implementations" or an Organisatie's contactpersonen count (note Organisaties is currently type:"custom"; converting it to type:"index" + config.cardComponent:"OrganisatieCard" is tracked separately — the OrganisationModal/AddContactpersoonModal/status-dialog flow around it is what keeps it custom for now).

Part of the fleet manifest-index wave (pipelinq #351, procest #436, scholiq #71). Non-production → auto-merge OK once CI is green.
