outreach: follow-up radar — deterministic "needs attention" + one-click draft (v0.1.0:69)

The Outreach page now opens with a "Needs attention" list. A deterministic scan
(outreach_agent.follow_up_radar) surfaces investors per the email history: tier 0 "you
owe a reply" (their email is the most recent, unanswered, >=3d), tier 1 flagged + quiet,
tier 2 warm lead gone quiet (no contact in >=45d). Most urgent first; every reason is
verifiable from the data (no LLM in the surfacing — the deliberate fix for the trust
problem that sank objection-grounding). Excludes graveyard; needs email history. One
click sets the investor + suggested type (follow-up/nurture) and runs the existing
outreach drafter. Route GET /api/outreach/radar. Test mcp/test_outreach.py extended
(owe-reply/warm-quiet/recent/graveyard/order). Verified live in preview.
