fix(markdown): change bold text color from blue to green (#323)

Changed the bold text (**text**) color in markdown rendering from ELECTRIC_BLUE
to CYAN_PRIMARY to match the green theme. The CYAN_PRIMARY color (#00FFA3) is
the primary accent color and provides better visual consistency with the rest
of the theme.

- Updated bold style to use CYAN_PRIMARY instead of ELECTRIC_BLUE
- Removed unused ELECTRIC_BLUE import from theme.rs
