Widen production columns that are narrower than the Hibernate mapping #92

Production Liquibase columns are shorter than the Hibernate mapping. Hibernate ddl-auto=validate still starts. These rows are INFO, not PROBLEM.

Measured 2026-10-19 with bash tools/scripts/compare-schema-drift.sh both --against jpa --fail-on none. Postgres: PROBLEM 0, INFO 60. Oracle: PROBLEM 0, INFO 63. STM_PAR_GS is not in the report. oracle_native_boolean is not in the report.

Character columns, both dialects (length_narrower_fixable):

• STM_TOKEN_USER.CODE_OTP 150 < 255
• STM_TREE.TRE_IMAGE_NAME 250 < 255
• STM_TREE_NOD.TNO_STYLE 50 < 255
• STM_TREE_NOD.TNO_VIEW_MODE 50 < 255

Oracle also reports STM_SERVICE_CHECK.SEC_OBSERVED 11 < 13 and STM_SERVICE_CHECK_SAMPLE.SCS_OBSERVED 11 < 13. Those are the timestamp type difference, tracked separately, not character columns to widen here.
