Rebalance launcher layout proportions

- Reduce primary button height 84→68 and font 20→17
- Reduce secondary nav buttons height 54→38 and font 15→13.5
- Compact status card padding and min height
- Remove Latin prefixes from nav button labels
- Adjust window height back to 260 to match reduced content
