ui: bitcoin text

[reez]

Is your feature request related to a problem? Please describe.

Could probably remove the orange “BITCOIN” on Home Screen - it’s redundant.

The bitcoin/sats unit is fire. I’d remove the BITCOIN logo to bring more attention to this.

Describe the solution you'd like
Remove

Additional context

• Remove "Bitcoin" text (Test that removal doesn't create some unnecessary UI change)

• Update screenshot for README
