docs: refresh README screenshots to v0.7.0

All four screenshots were taken against v0.1.0–v0.3.0 and showed the
old tabbed Run UI. Updated to the current stepper UI with:
- Dashboard: full EPG guide grid, both connections online, auto-updates panel
- Run: new Build Channels stepper (Setup/Export/Planner/Deploy), Nuke vs Add/Edit
- Channels: 27 named channels vs the old 10-entry placeholder
- Settings: visual refresh, correct version badge

Also removed stale 🆕 emoji from "The Planner" section heading.

 The heart of Programmarr. Instead of one mushy `Comedy (140)` channel, you build a lineup that feels **hand-programmed** — and you do it in a few clicks.
