feat: use digit wildcards for time range hotkeys

Replace 11 hardcoded time range actions with 6 dynamic actions using
use-kbd's digit wildcard capture feature (`\d+`). Type `3d` or `d3`
for 3 days, `2w` or `w2` for 2 weeks, etc.

Actions:
- `time:hours` - `N h` or `h N` for N hours
- `time:days` - `N d` or `d N` for N days
- `time:weeks` - `N w` or `w N` for N weeks
- `time:months` - `N m` or `m N` for N months
- `time:all` - `f` for full history
- `time:latest` - `l` for latest mode
