feat: Approvals Inbox, one cross-session queue for prompts waiting on a human

Permission dialogs, AskUserQuestion questions and idle prompts from every
session now land in a server-side inbox (web/approval-inbox.ts, one item per
session, claude-mode only) and are answerable in place: a header bell + drawer
on desktop, inline answer strips on the phone overview's NEEDS YOU rows, and
working push Approve/Deny buttons (previously dead ends, now answered straight
from sw.js with no tab open). Pending alerts survive reloads because the
frontend seeds from GET /api/approvals on init.

Answering sends the digit / Esc / prompt text through the existing tmux input
path; option digits are accepted only when they match options parsed from the
captured pane frame, and the answer path re-captures the pane first so a
dialog that already left the screen refuses with 409 instead of typing into
the composer. New elicitation_complete / elicitation_response hook matchers
resolve question items the moment they are answered in the terminal;
refreshStaleCodemanHooks heals existing cases.

Verified end-to-end against a live claude session: a real AskUserQuestion
dialog parsed into 5 option buttons and was answered from the drawer.
