Skip Fidelity Accounts that Start with "Y"

[NelsonDane]

Fidelity accounts that start with a Y are Fidelity-managed accounts and not available for manual trading. These should be skipped with this PR.

@matthew55 a manual exclusion list in .env would be better for me. block certain account numbers which means we don't have to make any changes in terms of account number exclusions in the future. If Fidelity every changes their naming scheme, blocking with a prefix of Y could mean changes are necessary in the future and doesn't necessarily exclude other accounts. We have crypto, charity, employer accts, etc that all could have their own naming scheme which blocking Y would do nothing for.

It would be nice, but that is too much work for now. This will work until then.
