CMMS fork: Phase 6 polish — schema.html light theme + load-time IndexedDB wipe

Browse source 
- cmms-bridge.js: wipeProjectData() clears the project object stores (devices,
  boards, components, images, overlappedImages, nets, schemas, schemaComponents
  — not the KiCad symbol library) and resets studio.js's shared globals before
  the CMMS attachment ZIP is imported. The ZIP is the single source of truth for
  a CMMS board, so restoreDevice()'s merge path (which only de-dupes on a newer
  meta.lastModified, absent on CMMS-created boards) no longer accretes duplicate
  image/net rows across repeated opens. init() also stamps data-theme=light as
  well as =dark. All gated on PCBRETRACE_CONFIG — standalone untouched.
- schema.html: inline head script mirrors ?theme=light|dark (passed by studio.js
  on the iframe src) onto <html> and, for light, injects cmms-schema-light.css.
  Full no-op with no ?theme=.
- cmms-schema-light.css (new): [data-theme="light"]-gated override of
  schema.html's :root palette for the CMMS light theme. Canvas stays dark.
- studio.js: append ?theme=<active> to the schema.html iframe src.
