Add "Set Anthropic API Key" StartOS UI action (v0.1.0:50)

Lets a non-technical operator install the Architect's Claude key from the
StartOS UI instead of the terminal: a masked text field whose value is written
to /data/secrets/anthropic-api-key (0600) on the box — the same file the
entrypoint already loads at boot. Secret is piped over stdin (never argv/env),
CR/LF stripped to match the entrypoint's read. allowedStatuses 'any'; a restart
is required (and stated in the action's warning + success message) since the
entrypoint reads the key only at startup.

Verified the Architect's data boundary first: the deployed Thesis Workshop
routes send only Ten31's own thesis text (thesis_lines/thesis_nodes) + the
partner-typed guidance to Claude — no contacts/lp_profiles/communications/grid.
(The MCP CRM-retrieval tools that DO return record substance are not wired into
the deployed Architect; the redaction boundary must land before any grounding
path uses them — Phase 1 Workstream D.)

tsc --noEmit clean.
