Change current frequency display text to BigFrequency for better visuals in the SignalHunter external app

[GitClo]

Brief description of what you did

I'm changing the current frequency text to be the now fixed BigFrequency for prettier aesthetics.

I didn't read yet but do you mind me asking if the number would been cut when frequency greater than 1GHz?
Cuz from the screenshot it looks like only works for sub 1GHz, but it's not me who wrote that big frequency so there might be some policy to move or tune size after digits reaches?

Hi, I tried 6ghz and as you can see it fits.

It removes up to 3 leading zeros.
Supports max frequency of 9999.999mhz (7 digits) and it centers based on the number of visible digits.
digit_pos = {(Coord)(screen_width - ((7 * digit_width) + 8) - (i * digit_width)) / 2, ...};

Thank you! Nice!

Pull request overview

This PR updates the SignalHunter external app’s main screen to use the existing BigFrequency widget for the current frequency readout, improving readability/visuals compared to the prior small Text display.

Changes:

• Replaced the main-view “current frequency” Text widget with a BigFrequency widget in HunterMainView.
• Updated view initialization and state update paths (on_show, focus, set_recording_state, update_frequency) to drive the new BigFrequency display and its style.
