fix(claudbg-eej6): wrap Handle::block_on with block_in_place in TUI
load_transcript_for_session and load_transcript_for_agent called
Handle::current().block_on() from within the tokio::main async context,
causing a panic on session selection. Wrap with block_in_place() to
signal the scheduler to move other tasks off the thread before blocking.
fix(claudbg-80fb): add #[serde(rename = "sessionId")] to RawEntry.session_id
The JSONL field is camelCase ("sessionId") but serde matched only the
literal field name, so session_id always deserialized as None. This made
AgentRef.session_id default to "", and since any_str.starts_with("") is
always true, load_transcript_for_agent matched the wrong session and
found no agent, leaving sub-agent transcripts permanently empty.
