Relating to Catastrophe Savings Accounts; expands allowable expenses

Added a new provision allowing self-insured individuals who do not obtain insurance on their legal residence to contribute up to $250,000 to a catastrophe savings account, limited by the value of their residence.

Modified contribution limits to differentiate between individuals with deductibles of $1,000 or less versus those with higher deductibles, creating tiered contribution caps based on deductible amounts.

Added a new requirement that taxpayers who receive a nontaxable distribution from a catastrophe savings account cannot make further contributions to any catastrophe savings account.

Modified the definition of qualified catastrophe expenses to clarify coverage for self-insured losses and ensure consistent terminology throughout the bill.

Corrected formatting and line breaks in the bill text, particularly in the definition sections and subsection headers.
