feat(ui/ux): unify typography to Pretendard and enforce read-only view mode as default

- Set global font-family to Pretendard and letter-spacing to -0.02em.
- Standardized table header font-size to var(--fs-sm).
- Fixed table clipping and sticky header behavior at 1920x1080.
- Implemented dynamic select options in search filters.
- Enforced 'view' mode as default for all asset modals (PC, Server, SW, etc.).
- Improved Modal logic to ensure all fields (including dynamic rows) are correctly locked.
- Updated Location View detail button from 'Edit' to 'View'.
- Updated design_rule.md to reflect new typography standards.
