feat(marksheets): finer typography and cleaner total-marks layout
- Admissions: Schools can now record and display the admission date on every student profile — useful for transfer certificates, RTE and government reporting, ID card printing, and "years in school" calculations across CBSE, ICSE, and State board admissions. Office staff can backfill the date for existing students, and the field shows up as a toggleable column on student lists. Hindi label एडमिशन दिनांक included for Hindi-medium schools in Tier-2 and Tier-3 cities. Part of the admissions module.
- Marksheets: Finer typography controls on printed marksheets — font picker, vertical stretch slider, and uppercase toggle on both label and value text. Especially useful for Hindi-medium and Devanagari marksheets across CBSE, ICSE, and State board templates where matras and shirorekha need extra headroom. Student-detail fields now reorder by drag-and-drop, the marks-table padding splits into independent top, right, bottom, and left controls (handy for pre-printed stationery), and the trailing Grade, Percentage, and Status columns nest cleanly under the consolidated Total Marks header in two-column marksheets. Part of the academics module.
