[Staking] Try State check warnings

[Ank4n]

https://github.com/polkadot-fellows/runtimes/actions/runs/23950822422/job/69861891325?pr=1114

Many repeated errors with following

1. Validator X has incorrect LastValidatorEra (expected 2131, got Some(2132))

Fixed by #11647

2. Nominator X has less stake (650000000000) than minimum role bond (2500000000000)

Older nominators from the time when Min Nominator Bond was lower.

3. pool X has incorrect ED frozen that can result from change in ED. Expected = 100000000, Actual = 10000000000. Use adjust_pool_deposit to fix it

These just indicate ED that was frozen in pool changed from 1 DOT to 0.1 DOT and pool owners can take back the extra deposit.

4. pool X has depositor Y with insufficient stake Z, minimum required is 5000000000000

Older pools when deposit required was lower than today.

2, 3 and 4 are expected, but not sure we can do much with the warnings. Maybe we should collect and report only the count so easier to notice if it increases.
