refactor: restructure auth config for better UX

Changed from flat structure to hierarchical read/write config:

Before:
  auth:
    enabled: bool
    required: bool
    allowed_npubs_read: []
    allowed_npubs_write: []

After:
  auth:
    read:
      enabled: bool
      allowed_npubs: []
    write:
      enabled: bool
      allowed_npubs: []

Three states per operation:
- enabled=false: no auth, allow all
- enabled=true, allowed_npubs=[]: auth required, any valid signature
- enabled=true, allowed_npubs=[...]: auth required, whitelist only

Much clearer semantics and easier to reason about.
