Regenerate bus schedule for 2026 Spring: adjust times and flags

[tiankaima]

Motivation

• Update the bus schedules and metadata to reflect the 2026 spring semester timetable and new source link.
• Apply several time adjustments and weekday/weekend flag changes for early departures across multiple routes.

Description

• Modified schedule generation logic data in tools/bus_data_gen.py by changing departure times and boolean weekend flags for several RouteScheduleP entries (notably rsA, rsB, rsC, rsE, and others) and updated the message text and source url to the 2026 spring reference.
• Regenerated the serialized schedule output at static/bus_data_v3.json, replacing the previous 2025 autumn data with the updated 2026 spring data.
• Kept route and campus definitions intact while only altering schedule times, weekend/weekday inclusion flags, and the data message/url metadata.

Testing

• Ran the generator with python tools/bus_data_gen.py to produce static/bus_data_v3.json, and the script executed successfully.
• Validated the produced JSON by loading it with python -c "import json; json.load(open('static/bus_data_v3.json'))", which succeeded without errors.
