fix(planner): waypoint-note tooltip no longer collapses to one char per line

The note tooltip's inner span was `display: block` with
`word-break: break-word` and no width, so the Leaflet tooltip sized itself
to the block's *min-content* — which under break-word is ~1 character —
and every character wrapped onto its own line (a tall vertical strip).

Switch to `display: inline-block` (sizes to content up to maxWidth, so it
stays one line when short and wraps at 220px when long) and the standard
`overflow-wrap: break-word`.
