Add fullscreen grid support and PDF preview in info panel

- Added fullscreen mode to grid and info panel components, including toolbar toggle and fullscreen styling.
- Introduced embedded PDF viewing in the info panel using PDF.js and a custom JavaScript viewer.
- Updated interfaces, CSS, and toolbar templates to support new features.
- Added new PDF asset (2_BANK  FRA.pdf) for document preview.
- Minor: Added local settings for Bash permission, fixed text encoding, and improved info panel table layout.
- No code changes in other referenced PDF files; added for informational or asset purposes only.
