fix: rename dashboardapi.{js,html} → dashboardAPI.{js,html}

Aligns the entry-file naming with the folder-name convention from
.claude/rules/node-architecture.md / superproject CLAUDE.md.

NON-BREAKING: the Node-RED type id stays lowercase
(`RED.nodes.registerType('dashboardapi', ...)`) so every deployed flow
that references this node continues to load. Only the file paths
change. Admin endpoints `/dashboardapi/menu.js` and
`/dashboardapi/configData.js` are unaffected — they follow the type
id, not the filename.

Updated:
- package.json `main` + `node-red.nodes` value
- test/basic/structure-module-load.basic.test.js require path
- CLAUDE.md: legacy-drift warning replaced with a note explaining the
  type-id preservation strategy

Same approach recommended for the remaining two legacy renames (mgc,
vgc); the superproject CLAUDE.md drift table now spells that out.
