refactor: clean up MemoryService to match actual API usage

Remove methods not used by any frontend or backend flow:
- get(), delete_index() (neither frontend uses; backend uses v1.1)
- ingest() (IM-internal, requires feedback_id from trace pipeline)
- patch_memory(), delete_memory() (wrong endpoints, IM admin ops)

Remove unused models: FeedbackMemoryStatus, EpisodicMemoryPatchRequest,
MemoryIngestRequest/Response, MemoryItemUpdateRequest/Response.

Add escalation memory methods used by the backend agentic loop:
- escalation_search() -> POST /api/Agent/memory/{id}/escalation/search
- escalation_ingest() -> POST /api/Agent/memory/{id}/escalation/ingest

Add models: EscalationMemoryIngestRequest, EscalationMemorySearchResponse,
EscalationMemoryMatch, CachedRecall (matching backend C# contracts).
