Support per‑radio‑card display of Caller ID

[djshadowxm82]

Summary

Add a “Caller ID” display on each radio card in RadioConsole2, with a new configuration option to toggle between inline (card) and overlay (drawer) views.

---

Motivation

• Operators need to see the incoming caller’s ID (radio call sign) at a glance on each channel card
• A configurable display mode lets users choose inline vs. drawer layouts based on screen real‑estate and workflow

---

Proposed Implementation

1. Configuration
   • Introduce a new CallLogFormat option ("card" | "drawer") in the settings file
   • Surface the option in the UI under Settings → Caller Log
2. UI Updates
   • Inline Mode (“card”): render a live Caller ID line at the bottom of each radio card with a collapsible log
   • Drawer Mode (“drawer”): add a collapsible bottom drawer that shows the full call log detached from the card
   • Add a “Call Log” toggle button in the navbar if in Drawer Mode.
3. Client Logic
   • Implement setupCallerLog(), toggleCallerLog(), and updateCallerId(cardId, callerId) in console/client.js
   • Wire the toggle button to update the display mode and persist the choice via readConfig() / saveConfig()
4. Styling
   • Update console/css/custom.css to accommodate the Caller ID line on cards and style the drawer overlay
   • Ensure responsive layouts and smooth transitions when toggling modes
