Expose the custom many-to-many CTag "Tags" relation as a linkMultiple
field (cTags) so it can be added to the list-view Search Filters, and
build the full Tags setup on Lead from scratch in parity with the others.
Opportunity / Contact / Account (relation already existed):
- add fields.cTags (linkMultiple) to entityDefs
- add cTags to the Search-Filters layout (Opportunity appended, preserving
cAccount1; Contact/Account get a full filters.json incl. cTags)
Lead (built from scratch):
- create Lead<->CTag many-to-many relation via EntityManager (relationName
cLeadTag, join table c_lead_tag); link normalized to cTags to mirror the
other three (API auto-prefix had produced cCTags)
- add cTags field, de_DE/en_US labels, clientDefs panel polish (create:false,
unlink-only row actions), bottomPanelsDetail entry, and filters.json
- CTag side: links.interessenten label de "Interessenten" / en "Leads"
Verified via API/DB: cTags linkMultiple present on all four scopes; Lead
link/CTag.interessenten resolve; Any of / All of / None of filters execute
and return correct results end-to-end; existing data intact.
