fix(ui): save memory config to spec.declarative.memory

[onematchfox]

Memory was being written to spec.memory on the Agent CR, but the v1alpha2 CRD defines memory under spec.declarative, not at the top level of AgentSpec - see

kagent/go/api/v1alpha2/agent_types.go

. The backend silently ignored the misplaced field, causing memory configuration to appear to save but never actually persist.

Also removed a dead fallback in the edit-load path that attempted to read spec.memory (a field that never exists in v1alpha2) masking the underlying issue.

Pull request overview

Fixes Agent memory persistence in the UI by aligning the payload and edit-load logic with the v1alpha2 Agent CRD, where memory is nested under spec.declarative (not at top-level spec).

Changes:

• Write memory configuration to spec.declarative.memory when building the Agent payload.
• Remove the (dead/legacy) edit-load fallback that attempted to read spec.memory.
