Cs 9965 links spec and update spec should use get dependencies to support

[lucaslyl]

Problem:

1. Realm.ts had two similar endpoints that caused confusion:

• /_dependencies - JSONAPI format, supports instances and modules
• /_card-dependencies - JSON array, instances only (renamed in this PR to
  distinguish these two APIs: /_dependencies → /_card-dependencies)

2. The /_card-dependencies endpoint only supports instances, not modules.

Changes

1. Renamed one of the /_dependencies endpoints → /_card-dependencies to
   distinguish the two APIs.

2. Update listing-create(linkSpecs) and listing-update-specs to use /_dependencies instead
   of /_card-dependencies to support both instance and module dependencies.

   • Parse JSONAPI response format (data[].attributes.dependencies)
   • Update Accept header to JSONAPI mime type
   • Extract dependencies from all entries in the JSONAPI data array

This clarifies endpoint usage and enables module dependency support.

@richardhjtan I will rename this to card-dependencies to better distinguish its API purpose
