feat: Customize hub + roles editor, terminal logo, invite links

IA refactor and the custom-roles editor pass 11 left as data-only.

Customize hub:
- New /customize (admin/board) with a left section rail: Roles,
  Membership tiers, Areas, Invite codes, Onboarding.
- One focused module per panel under app/(app)/customize/panels/
  plus a shared card and types file. The client shell is ~75 lines;
  each panel is self-contained (smart separation of concerns).
- Settings slimmed to Space, Integrations, Webhooks. Removed the
  Roles/Tiers/Invites/Onboarding tabs and the Areas block from
  settings-client.tsx (~700 lines) and the matching fetches from
  settings/page.tsx. Dead props/state/types removed.
- Sidebar: added a Customize NavLink (admin/board).

Roles editor:
- Rename/recolor the five built-in roles (upsertRoleLabel) and full
  CRUD on custom org roles. Adds the read path the audit flagged as
  missing: lib/role-labels.ts (getRoleLabelMap/roleDisplayName) is
  consumed in (app)/layout.tsx so the sidebar shows the renamed role.

Logo:
- Reverted the brand mark to the terminal >_ glyph
  (components/brand-mark.tsx) on the landing nav/footer, onboarding
  header, and favicon (public/logo.svg). Removed the dead local
  IcoTerminal. AtlasLogo stays only on the resources project page.

Invite links:
- InvitesPanel has Copy code and Copy link (/signup?invite=CODE).
  signup reads ?invite= on mount, prefills the code, preselects join.

Deferred and tracked in HANDOFF: types/database.ts sync, renamed-role
display on the members table, splitting the still-large
settings-client.tsx, custom-role assignment UI.

266/266 tests pass. Production build clean; /customize, /onboarding,
slimmed /settings all in the route table. No migration this pass.
