feat: per page ops calibration

[cusma]

This PR adds opcodes budget calibration to ensure sufficient per-page budget

[Copilot]

Pull request overview

This PR adds per-page opcodes budget calibration to ensure sufficient computational budget for operations that scale with metadata page count. The changes introduce budget allocation calls for hash computation operations and add a test suite to validate budget sufficiency across all possible page counts.

• Adds ensure_budget calls to _compute_header_hash and _compute_page_hash methods with calibrated budget values
• Introduces pages_min_fee helper function to calculate appropriate transaction fees based on page count
• Adds parametrized test covering all page counts from 0 to MAX_PAGES (31)
