feat: add UNDERLINE bitflag to EpdFontFamily::Style

Browse Source 
Convert Style enum to true bitflags by adding UNDERLINE=4. Update getFont()
to use bitwise operations instead of equality checks, allowing styles like
BOLD|UNDERLINE to work correctly.

This is preparation for encoding underline state directly in the Style
rather than tracking it separately.
