E2e update

[shamil-gadelshin]

This PR adds staking package to e2e workflow (using fast-runtime binary). It covers happy paths for the extrinsics:

• add_stake
• add_stake_limit
• remove_stake
• remove_stake_limit
• remove_stake_full_limit
• unstake_all
• unstake_all_alpha
• move_stake
• transfer_stake
• swap_stake
• swap_stake_limit
• root_claim (all RootClaimType)
• set_root_claim_type
• sudo_set_num_root_claims
• sudo_set_root_claim_threshold

I would recommend using expect instead of assert because assert is too generic while expect will allow vitest (the test runner) to capture the values and give more explicit failure messages (https://vitest.dev/api/expect.html)

assert.ok(a > b, "Some message")

AssertionError [ERR_ASSERTION]: Balance should increase after stake move

expect(a, "Some message").toBeGreaterThan(b)

Balance should increase after stake move

expect(received).toBeGreaterThan(expected)

Expected: 500n
Received: 300n
