feat: point vehicle location markers along their SIRI bearing

[arielvino]

Description

• GPS markers appear as directional arrows - carrying the bearing angle.
• Added a race-flag marker for the last GPS ping.
• Markers carry the velocity in 2 ways: higher velocity appear as a bigger arrow, and the lower half of the velocity scale appear red instead of black.
• Special marker for a 0-velocity bus.
• z-index - from the front to the back: start/end markers, stopped-bus, markers by velocity slowest-to-fastest, bus stop markers. This way it is easy to spot areas where the bus was slow or stopped.

As a side effect it added a ring to the time-based-map bus icons too (caught by Applitools).
It is not necessarily bad (and even arguably better) so I left it as is:

@NoamGaash
I took inspiration from your older idea, after you told it in the hackathon.
I think it fit well on the single-line page.

the code has many trivial comments in it, I think we should consider adding a CLAUDE.md rule to prevent this.

other than that - it's a very cool feature, and I'm glad you've developed it! 👏 nice idea
