Use N intervals across an N-bin IQ FFT span. Share bin windows and frequency conversion across spectrum rendering, waterfall columns, and peak-jump tuning. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Use containing FFT intervals for cursor and marker lookup. Extend the final rendered interval and derive waterfall columns from each drawn row. Use captured-frame coordinates for lab peaks and recall. Address the approved geometry review of musithang#12. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

This PR prepares sdrtop for spectrum analyzers that publish measured power bins. It is one of three independent prerequisites for #7.
Spectrum and waterfall views used different bin intervals. A bin could therefore map to a different frequency or canvas position across consumers.
This PR introduces one bin-axis model and routes existing IQ geometry through it. #7 uses the same model for direct power traces.
