feat(dashboard): split monolithic CSS into common + per-page bundles

dashboard.css was 2500+ lines covering every page. Split into four
separate esbuild entry points:

- common.css  — @hive/shared imports + shared typography, badges,
                buttons, inbox/compose, side panel, diff panel,
                path linkification, logs-header chrome (shared by
                flow + logs)
- dashboard.css — dashboard-only styles (tabs, container rows,
                  approvals, questions, permissions, schedules, etc.)
- flow.css    — flow page chrome (frosted header, composer, inbox pill)
- logs.css    — log viewer sub-tabs (journal-*, build-logs-*)

Each HTML file now loads common.css + its own page-specific bundle.
build.mjs updated to produce all four CSS outputs. All builds pass.

Closes #1056
