Jason 34ecaf360b feat: rename Tkinter dashboard to GUI_V65_Tk, add replay/demo/targets parity
Rename radar_dashboard.py -> GUI_V65_Tk.py and add core feature parity
with the v7 PyQt dashboard while keeping Tkinter as the framework:

Replay mode:
- _ReplayController with threading.Event-based play/pause/stop
- Reuses v7.ReplayEngine and v7.SoftwareFPGA for all 3 input formats
- Dual dispatch routes FPGA control opcodes to SoftwareFPGA during
  raw IQ replay; non-routable opcodes show user-visible status message
- Seek slider with re-emit guard, speed combo, loop checkbox
- close() properly releases engine file handles on stop/reload

Demo mode:
- DemoTarget kinematics scaled to physical range grid (~307m max)
- DemoSimulator generates synthetic RadarFrames with Gaussian blobs
- Targets table (ttk.Treeview) updates from demo target list

Mode exclusion (bidirectional):
- Connect stops active demo/replay before starting acquisition
- Replay load stops previous controller and demo before loading
- Demo start stops active replay; refuses if live-connected
- --live/--replay/--demo in mutually exclusive CLI arg group

Bug fixes:
- seek() now increments past emitted frame to prevent re-emit on resume
- Failed replay load nulls controller ref to prevent dangling state

Tests: 17 new tests for DemoTarget, DemoSimulator, _ReplayController
CI: all 4 jobs pass (167+21+25+29 = 242 tests)
