fix(jira): correct Data Sensitivity field ID and replicate Jira's real classification scheme

The auto-create-ticket call was sending customfield_11233 (a field that
doesn't exist in the project) instead of the real Data Sensitivity field
customfield_11814, which made Jira reject the WHOLE issue and silently
block ticket creation for every new test.

Also replaces Aegis's invented 4-tier data_classification scheme
(public_release/general_use/confidential/restricted) with the 6 values
Jira's Data Sensitivity field actually uses (public/general_use/
internal_use_only/trusted_people/customer_content/pii), since that is
the classification the organization actually applies. Includes a data
migration remapping existing rows and a defensive retry if Jira ever
rejects an unscreened custom field again.
