Feature/analysis tools UI improvements

[Barneyjm]

Summary

• Added advanced analysis algorithms: AFR Analysis (Fuel Trim Drift CUSUM, Rich/Lean Zone Detection, AFR Deviation), Derived Calculations (Volumetric Efficiency, Injector Duty Cycle, Lambda), and professional-grade Butterworth Filters (lowpass/highpass with SOS implementation)
• Added channel selection dropdowns with helpful tooltips showing common ECU channel names for each analyzer type
• Moved Results section to top of Analysis Tools window for better visibility
• Added "Run & Chart" button for one-click workflow (run analysis and add to chart immediately)
• Added Min/Max display with jump buttons for computed channels (matching regular channel functionality)
• Added computed channel indicator ("ƒ" symbol) in channel cards to distinguish formula-based channels

Test plan

• Open Analysis Tools window and verify Results section appears at top when results exist
• Run any analyzer and verify "Run & Chart" button adds result to chart immediately
• Check that channel dropdowns show tooltips with common ECU channel names
• Add a computed channel and verify it shows Min/Max values with jump buttons
• Verify computed channels display the "ƒ" symbol indicator
• Test Butterworth filters with different orders (1-8) and verify no NaN values
