kempersc 0393b321c9 refactor(schema): unify custodian_type slots into has_or_had_custodian_type (Rule 39, 43)
- Migrate 236+ class files from custodian_types to has_or_had_custodian_type
- Archive deprecated slots: custodian_type, custodian_types, custodian_type_broader/narrower/related
- Update main schema and manifest imports
- Fix Custodian.yaml class to use new slot
- Fix annotation format (list→scalar) in has_or_had_custodian_type.yaml

Rules applied:
- Rule 39: RiC-O naming convention (hasOrHad pattern)
- Rule 43: Slot nouns must be singular (multivalued:true for cardinality)
- Rule 38: Slot centralization with semantic URI

\ heritage custodian.\n\n**CRITICAL DISTINCTION - THREE-TIER DIGITAL PLATFORM\
\ MODEL**:\n\n1. **DigitalPlatform** (main digital entry point):\n - Primary\
\ web presence of the custodian\n - Main website, primary API, flagship digital\
\ platform\n - Like CustodianPlace is the preferred place reference\n -\
\ Examples: rijksmuseum.nl, europeana.eu, nationaalarchief.nl\n \n2. **AuxiliaryDigitalPlatform**\
\ (subordinate platforms) - THIS CLASS:\n - Secondary digital properties:\
\ project sites, exhibition microsites\n - Like CustodianAppellation is to\
\ CustodianName\n - Examples: project websites, temporary exhibition portals,\
\ specialized tools\n \n3. **DigitalPlatformType** (custodian type classification):\n\
\ - For digital-FIRST custodians (no physical building)\n - Applied at Custodian.custodian_type\
\ level\n - Examples: Europeana (aggregation platform), Internet Archive\n\
\n**DCAT ALIGNMENT**:\n\n`dcat:Catalog` - \"A curated collection of metadata\
\ about datasets\"\n\nKey properties:\n- `dcat:dataset` - links to datasets/collections\n\
- `dcat:service` - data services provided\n- `dcterms:isPartOf` - links to parent\
\ catalog\n\n**RELATIONSHIP TO DIGITALPLATFORM**:\n\nAuxiliaryDigitalPlatform\

\ Portal (thematic project)\n\n2. **Exhibition Microsites**:\n - Temporary\
\ exhibition with dedicated website\n - Virtual tour for specific collection\n\

\ **Legacy/Archived Platforms**:\n - Previous website versions\n - Deprecated\
\ APIs still in use\n\n5. **Grant-Funded Projects**:\n - EU-funded digitization\

- JavaScript libraries or framework signatures
- Admin panel detection
**Values**:
- true: CMS backend detected (see powered_by_cms for identity)
- false: No CMS detected (likely static site or custom-built)
- null: Detection not performed or inconclusive
**Use Cases**:
1. "Does this auxiliary platform have a known CMS?" → Check cms_detected
2. Technical survey: Identify platforms needing CMS identification

- If cms_detected = true and powered_by_cms is null → CMS detected but not identified
- If cms_detected = false → powered_by_cms should be null
**Use Cases**:
1. "What CMS powers this project website?" → Follow powered_by_cms
2. "What auxiliary platforms use this CMS?" → Reverse query
3. Platform inventory: Map all CMS deployments across institution
