fix: Resolve debug settings bottom sheet crash on some devices (#474)

Fixes #472 - App crashing in debug settings
The issue was in ui/debug/DebugSettingsSheet.kt:
- Line 304: Code was pre-formatting double value with String.format() then passing
  to string resource that expected raw double parameter
- Line 307: Numeric values weren't properly converted to strings for string resource
  that expected string parameters
Changes made:
- Changed stringResource(R.string.debug_target_fpr_fmt, String.format("%.2f", gcsFpr))
  to stringResource(R.string.debug_target_fpr_fmt, gcsFpr) - passes raw double value
- Changed stringResource(R.string.debug_derived_p_fmt, p, nmax)
  to stringResource(R.string.debug_derived_p_fmt, p.toString(), nmax.toString()) -
  properly converts numeric values to strings
This resolves the IllegalFormatConversionException: f != java.lang.String crash
when scrolling through the debug settings bottom sheet.
