Split GraphQL schemas into per-entity files

Split each API's monolithic schema.graphql into per-coredata-model
files under graphql/ subdirectories. gqlgen's follow-schema layout
with {name}.resolvers.go template generates one resolver file per
schema file. Relay uses schema + schemaExtensions to load the split
files.

Connect API: 8 files (base, session, organization, profile,
personal_api_key, saml, scim, audit_log)

Trust API: 5 files (base, trust_center, auth, nda, mailing_list)

Console API: 25 files covering all domain entities

Types extended across files (Organization, Mutation, Viewer,
TrustCenter, Identity) are defined in base.graphql as required by
Relay's schemaExtensions.
