v0.5.44

Routers page card improvements

Added

• Disk usage bar on router cards (src/index.js, public/app.js) — each router card on the Routers Overview page now shows a Disk bar below RAM, using the same orange (#fb923c) colour as the storage gauge on the main dashboard, with the same warn (>75%) and crit (>90%) thresholds

Changed

• Router cards pre-load at startup (src/overviewSessions.js) — background router sessions now start their collectors immediately on connect instead of waiting for the first page visit; Routers page cards show data instantly on first navigation
• Router card header (public/app.js) — animated status dot replaced with a WiFi SVG icon (green when connected, red when offline); configured IP address shown as a pink (#ec4899) subtitle below the router name (suppressed when the label is the same as the host); card title forced to color:inherit to match body text white
• Router card stat values (public/app.js) — Uptime and Clients values bumped from .82rem to .9rem; Clients value coloured #a855f7 (bright purple)
