Adds full parity with Deezer/Qobuz/Tidal/Discogs in every dashboard
UI layer — orb button, live tooltip, WebSocket push, rate speedometer.
- webui/index.html: Amazon enrichment orb button after Discogs
- webui/static/amazon.svg: local icon (a + smile, same pattern as
hydrabase.png — avoids external URL dependency)
- webui/static/style.css: Amazon button/spinner/tooltip CSS with
FF9900 brand color; added to mobile tooltip suppress list
- webui/static/worker-orbs.js: Amazon orb in WORKER_DEFS [255,153,0]
- webui/static/api-monitor.js: Amazon in rate gauge services list,
label, and color map
- webui/static/enrichment.js: updateAmazonEnrichmentStatusFromData,
toggleAmazonEnrichment, DOMContentLoaded init + 2s poll
- webui/static/core.js: socket.on enrichment:amazon-enrichment listener
- web_server.py: amazon-enrichment added to _emit_enrichment_status_loop
workers dict so WebSocket pushes fire every 2s
