Add Verisoo attest/verify web MVP — full attestation lifecycle

Browse Source 
Attest page (/attest):
- Image upload with optional caption and location
- EXIF auto-extraction toggle
- Creates Ed25519-signed attestation record
- Stores in verisoo append-only binary log + LMDB index
- Displays: record ID, attestor fingerprint, timestamp, image hashes

Verify page (/verify):
- Image upload for verification against local attestation log
- SHA-256 exact matching + perceptual hash matching (pHash, dHash)
- Shows match type (exact/perceptual), hash distances, attestor info
- Color-coded distance badges (green=0, info<5, warning<10, danger>=10)

Attestation log (/attest/log):
- Lists recent attestations with short ID, attestor, timestamp, SHA-256
- Shows total record count

Verified: full lifecycle works — attest image → verify same image → exact match found
