feat(panel): dense tooltip pass — projects, products, social, KB, business, settings, notifications (178 tips)

Density bar: every dialog field, column header, filter, badge, and
status pill explains itself — grounded in the backend (ladder
normalization, rate-limit park/probe, self-hosted fallback, reindex
scope). Disabled buttons span-wrap so tips fire; tabs re-assert
data-state.
