fix: add data validate missing verification

[ANISH-SR]

Summary of Changes

• Added the missing data.validate()? call in process_set_globalconfig, ensuring GlobalConfig is validated before computing size or writing to the account.
• imported the Validate trait into the processor so GlobalConfig::validate is available.
• This aligns SetGlobalConfig with the validation pattern used by other state-setting processors.

Testing Verification

• Build succeeds and SetGlobalConfig now rejects invalid GlobalConfig values via validate().
• rust-lint also passes w/o errors

Fixes #2239

Can you add an SVM program test to confirm that validate catches invalid input when this instruction is called? Thank you

Hi @karl-dz , just pushed some new changes w/ SVM tests. Can you please review this? Thanks

For some reason there is a go-lint error. Can you rebase and push to your branch? I can run the workflows again when you do. Thank you
