fix(security): SSRF URL validation (#1130) + redactSecrets on memory admin endpoints (#1131, #1132)

Browse Source 
URLs returned from DB and Redis cache (db.GetCachedURL, workspaces.url column)
are now validated via validateAgentURL() before any HTTP request is made:

- mcpResolveURL (mcp.go): added validateAgentURL() calls on all three return
  paths (internal cache, Redis cache, DB fallback).
- resolveAgentURL (a2a_proxy.go): added validateAgentURL() call before
  returning agentURL to the A2A dispatcher.

validateAgentURL() was extended (registry.go) to resolve DNS hostnames and
check each returned IP against the blocklist (private ranges, loopback,
cloud-metadata 169.254.0.0/16). "localhost" is allowed by name for local dev.

GET /admin/memories/export now applies redactSecrets() to each content field
before including it in the JSON response. Pre-SAFE-T1201 memories (stored
before redactSecrets was mandatory on writes) no longer leak credentials.

POST /admin/memories/import now calls redactSecrets() on content before both
the deduplication check and the INSERT. Imported memories with embedded
credentials cannot bypass SAFE-T1201 (#838).

- admin_memories.go: GET /admin/memories/export + POST /admin/memories/import
  handler (from PR #1051, with security fixes applied).
- admin_memories_test.go: 6 tests covering redactSecrets parity on both endpoints.

- registry_test.go: added DNS-lookup test cases for validateAgentURL (F1083).
  "localhost" allowed by name (preserves existing test); nxdomain blocked.
