refactor(org): drop legacy adapterLabels / claude_compat fallback; unify connector label resolution

OrgChart and AgentRoster both carried a `claude_compat`-prefix fallback
chained against `adapterLabels[connectorId] ?? connectorId` to paper
over the pre-pi-mono connector id space (claude_local / codex_local /
gemini_local / claude_compat_2..10). The migration to pi-mono's catalog
retired those ids months ago — the fallback is dead code that still
runs `String.prototype.startsWith` on every render and forks the label
resolution into two subtly different shapes in two files.

Replaced with `formatConnectorLabel(connector, fallbackId)` in
lib/formatters.ts, used by both OrgChart and AgentRoster.

Also in this commit (typography polish bundled because touching the
same render paths):

- OrgChart connector label: 9px uppercase tracking-0.08em → 11px
  tracking-tight. The 9px chip was unreadable at default zoom.
- OrgChart zoom controls: `+` / `−` / "Fit" mixed text + character ops
  replaced with Plus / Minus / CornersOut icons (imported from the
  existing icon barrel) + a focus-visible ring for keyboard users.

No rendering changes for the non-cosmetic path (status dots, card
layout, edges). The removed `adapterLabels` map was exported from
orgTreeLayout.ts and had no other importers.

Covers J1 / J3 / J4 / J6 from the team-page audit.
