chore: Use schedule to launch L1 related services and tasks

[janjakubnanista]

Description

Very plug-here-plumb-there PoC of integration of the launch scheduler with the existing code.

Due to how we pass the arguments around, the L1 setup has been split into several atomic pieces that come together under the l1 name.

If used like this, this PR reveals the need for:

• Dependency aggregator helpers - something that will just gather dependency outputs under a struct
• Logging helpers - something that will wrap a particular item with before/after logs

Of course, the IDs should not be hardcoded all over the place, and the main.star should not be doing low-level work like this. But remember, PoC.
