Merge Bitcoin categories into one; rename Self-Hosted Apps to Personal Apps

- One "Bitcoin" category: the service catalog distinguishes bitcoin-base
  from bitcoin-apps, which surfaced as two sidebar menus and two tile
  sections. The Hub now normalizes both into a single "Bitcoin" category
  (nav item with combined count, one tile section). CATEGORY_ALIASES in
  constants.js maps the catalog keys; server config sends one
  ("bitcoin", "Bitcoin") entry and the node role allowlist is updated
  to match. The nix catalog is unchanged.
- "Self-Hosted Apps" is now "Personal Apps" — every service here is
  self-hosted, so the label added no distinction.
