add dolibarr api skills for read-only inspection

First two of an expected family of dolibarr-* skills:

- dolibarr/: platform reference — DOLAPIKEY auth, the voir_tous ACL
  trap, endpoint catalogue, the dol-curl.sh wrapper, .env credentials
  layout (gitignored, mode 600). Every future workflow skill depends
  on this one.
- dolibarr-invoice-audit/: first workflow — list KissMetrics invoices,
  audit one invoice end-to-end (JSON facts + PDF mandatory-mention
  checklist against the French legal corpus), audit the KissMetrics
  thirdparty record.

Live captures in examples/ include real audit findings to surface
to the Arcodange × KissMetrics cohort review: PDFs are missing
capital social, L.441-10 penalties, 40 € indemnity, L.123-22 / R.123-237;
KissMetrics thirdparty has no EIN (idprof1..6 all empty);
static/config/company.json holds placeholder values and a wrong
forme juridique (claims SAS, the real Dolibarr is SARL).

.gitignore hardened with *.credentials, secrets/, *.key, and an
explicit .claude/skills/**/.env pattern.
