fix: undelegation exceeded computational budget (#287)

# Description

- fix: delegation exceeded computational budget

<!-- greptile_comment -->

## Greptile Summary

Increased compute budget constants in
`magicblock-accounts/src/remote_account_committer.rs` to prevent
transactions from failing during delegation operations.

- Increased `BASE_COMPUTE_BUDGET` from 60,000 to 80,000 CUs for base
transaction overhead
- Increased `COMPUTE_BUDGET_PER_UNDELEGATION` from 45,000 to 70,000 CUs
to accommodate higher computational needs during undelegation
- Maintained `COMPUTE_BUDGET_PER_COMMITTEE` at 45,000 CUs for standard
committee operations
- Integration tests in
`/test-integration/schedulecommit/test-scenarios/tests/` validate the
changes work with the new compute budgets
