Implement cell merging and enhanced weekend formatting

- Add horizontal cell merging for header rows (2-5) using jspreadsheet setMerge
- Day names, year, month, and day values now span across both day/night columns
- Extended weekend highlighting to year/month/day rows under weekend days
- Improved visual hierarchy with grouped date information per day
- Fixed font sizes for better readability (12px for all rotated values)
- Increased day names row height to 50px for better text fit
- Removed bold formatting from "den"/"noc" shift labels

Technical improvements:
- Correct jspreadsheet v4 setMerge syntax: setMerge(cellAddress, colspan, rowspan)
- Excel-style column naming supports AA, AB, AC... format
- Preserved all text rotation and color formatting during merging
