fix: add shared staticDirectories to all standards sites

- Add staticDirectories configuration to all standards sites (ISBDM, LRM, FRBR, isbd, muldicat, unimarc)
- Each site now includes both local static directory and shared theme static directory
- Enables access to shared graphics like logo-ifla_black.png and cc0_by.png across all sites
- Portal already had correct path structure, standards sites use ../../packages/theme/static
