feat(tours): complete planner follow-up scope

This commit completes the reviewed Tours follow-up scope after the Tours MVP was merged into dev.

Included feature blocks:

- RC-01: identify Tours in PLAN day rows and show compact Tour facts;
- RC-06: search for a city or address in TOUR-PLANNER without hidden writes;
- RC-07: reorder Tour waypoints in the left sidebar;
- RC-08: drag Tour waypoints on Leaflet, MapLibre and Mapbox with stable viewport, history and routing behavior;
- RS-01: persist Tour descriptions and HTTPS information links with local provider classification;
- RS-02: persist breaks/additional time and calculated or manually adjusted planned Tour duration without changing scheduling semantics.
The implementation preserves:

- ordinary Place and Legacy Track behavior;
- Tours-off fallback behavior;
- existing GPX/import behavior;
- Tour assignment and deletion behavior;
- calculated routing duration as a separate value;
- existing Tour provenance fields;
- keyboard/list alternatives for waypoint editing.
Not included:

- PR1-09 trip-wide Tour summary;
- Wanderer integration;
- GPX import changes;
- new Tour types;
- Tour-to-Day drag-and-drop;
- further roadmap or Post-Release features.
Validation:

- focused RC-01/RC-06/RC-07/RC-08/RS-01/RS-02 tests passed;
- affected shared/server/client typechecks passed;
- migration and generated DB type checks passed;
- scoped ESLint passed;
- staged diff checks passed;
- owner manual tests passed for all six feature blocks.
