Add generic eSign portal for all compliance document types

Reusable signing flow: service handler generates document → inserts
esign_records row → emails JWT link → client reviews PDF + signs →
API stores signature + resumes pipeline. Works for RMD, CPNI, CALEA,
499-A engagement, discontinuance, CRTC, and any future doc types.
