Fix for bug #30782: Truncated UNSIGNED BIGINT columns only in SELECT w/ CASE,
JOIN, and ORDER BY
Problem: improper maximum length calculation of the CASE function leads to
decimal value truncation (storing/retrieving decimal field values).
Fix: accurately calculate maximum length/unsigned flag/decimals parameters
of the CASE function.
