[LocalNet] Fix sequencer hot reloading

[okdas]

Objective

Hot-reloading (quick restart after the code is updated) currently doesn't work.

Origin Document

Conversation starting from this comment.

We are using helm_resource extension for Tilt which doesn't seem to work well with Hot Reloading (more info). We've had a similar set-up work in another repo, but it was using Tilt's helm() function - example. We can switch to that implementation for poktroll repo as well.

Goals

• Sequencer process restarts automatically after code is changed.

Deliverables

• Switch to Tilt's helm() instead of helm_resource extension.

General deliverables

• Comments: Add/update TODOs and comments alongside the source code so it is easier to follow.
• Testing: Add new tests (unit and/or E2E) to the test suite.
• Makefile: Add new targets to the Makefile to make the new functionality easier to use.
• Documentation: Update architectural or development READMEs; use mermaid diagrams where appropriate.
