* chore: upgrade pdmt5 to v1.0.4
pdmt5 1.0.4 removes Mt5TradingClient/Mt5TradingError entirely and wraps
Mt5Config.password in pydantic SecretStr. Drop the now-dead conditional
Mt5TradingError handling in mt5cli.exceptions/sdk/retry (mt5cli already
type-checks trading clients against its own protocol, so no functional
change), and unwrap SecretStr when forwarding a base config's password to
per-account configs. Update tests and docs accordingly.
* chore: declare pydantic as a direct runtime dependency
mt5cli.sdk imports SecretStr directly from pydantic, so pin it explicitly
instead of relying on pdmt5's transitive dependency.
