adebisi-fa 14f6fd6a8e feat(fpagent): authenticate the wizard's a2loft calls with the session token
The fingerprint wizard's staff-lookup and fingerprint-save proxies forwarded the page's OTP with the session phone. a2loft resolves that phone against the domain being addressed, so an operator who holds only capture_biometric was rejected unless they were a domain super-user. The cropper already saves with the session token.

- tools/server.js: both a2loft proxies send Authorization: Bearer <session token>, no phone/otp; validateProxy drops the OTP and phone checks.
- tools/public/assets/fp: both OTP fields, otpLookup/otpSave state, request params and resets removed; canLookup/canSave no longer gate on OTP.
- Tests assert the Bearer header, no query auth, no OTP field in the served page, and both gates without a credential (66/66 pass).
- README and Help page updated.

Requires the a2loft fingerprint-token-auth change deployed first. OpenSpec change: fingerprint-token-auth.

# Proposal: fingerprint-token-auth
## Why
The Fingerprint Agent wizard's two a2loft calls — staff lookup and fingerprint
save — prove the operator with a phone number and an OTP forwarded through
same-origin proxies. a2loft resolves that phone against the domain being
addressed, so an operator who holds the OpenFGA `capture_biometric` relation
but is not a super-user of that domain's uploader list is rejected. The cropper
already saves with the session's PocketBase token; the wizard's a2loft calls
should use the same token flow.
## What Changes
- The `/api/:domain/staff/:reference` and
`/api/:domain/staff/:reference/fingerprints` proxies send the session's
PocketBase token as an `Authorization: Bearer` header instead of forwarding
`phone`+`otp` query parameters.
- The OTP validation is removed from the proxies; the session token is the
credential.
- The wizard's lookup and save steps drop their OTP fields and OTP state.
- The Fingerprint Agent and tools-app specs, the README, and the Help page are
updated.
- Requires the a2loft `fingerprint-token-auth` change deployed first.
## Capabilities
### New Capabilities
(none)
### Modified Capabilities
- `fingerprint-wizard`: the two-finger enrollment flow and the per-call OTP
requirement become token-authenticated.
- `tools-app`: the a2loft proxies requirement now injects the session token
instead of forwarding `phone`+`otp`.
## Impact
- `tools/server.js`: the two a2loft proxy handlers and `validateProxy`.
- `tools/public/assets/fp/index.html`, `tools/public/assets/fp/app.js`: the OTP
fields, state and request parameters removed.
- `tools/test/server.test.js`: proxy assertions.
- Documentation: README and the Help page.
