fix(jira): widen _tool_jira_issues.fix_versions column to text

The fix_versions column in _tool_jira_issues was originally created as
varchar(255) by migration 20250619, but the JiraIssue model was later
changed to type:text without a corresponding migration to alter the
existing column. On existing databases the column stayed varchar(255),
causing the extractIssues subtask to fail when an issue's joined
fix-version names exceed 255 characters:

  Error 1406 (22001): Data too long for column 'fix_versions'

Add migration 20260707_change_fix_versions_to_text to alter the column
to text, matching the model definition and the domain-layer issues
table, and register it in migrationscripts/register.go.
