Fix tack detection and convert track detail to embedded-map fragment

TackDetector: revert STABILITY_MAX to 30° (was tightened too far to 20°),
add 120s start-skip to filter GPS cold-start false positives, keep 45s
minimum gap between tacks.

TrackDetailSheet: convert from BottomSheetDialogFragment to a regular
Fragment with an embedded MapLibreMap in the top half. This fixes the
map centering issue (the embedded map is always sized to its own frame),
eliminates accidental dismissal when dragging the map, and makes the
view self-contained — back navigation restores the track list via the
fragment back stack. Tack markers rendered on the embedded map; tapping
a log event pans the embedded map directly.
