test: add get_stakers switch flow

[arad-starkware]

This change is 

---

Note

Adds a test covering get_stakers behavior when a delegator switches delegation between stakers across epochs, and cleans up flow ideas.

• Tests:
  • Add get_stakers_switch_delegation_flow_test in flow_test/test.cairo to verify get_stakers weights across epochs during full exit intent and stepwise delegation switches between two stakers.
• Docs:
  • Trim flow_test/flow_ideas.md by removing the obsolete get_stakers idea section.
