VIOLET V1a: dolphin_violet DDL set + statement-wise applier (applied + verified)

14 tables consolidated from the LIVE post-ALTER dolphin_pink schema
(maras_tp + provenance folded into base CREATEs — a fresh DB never replays
ALTER chains) + violet_feed_divergence (scan-vs-venue divergence metric,
session_id + plane seqs + mono_ns). apply_violet_ddl.py posts ONE statement
per HTTP request (multi-statement posts fail — proven on pink 08), is
idempotent (all IF NOT EXISTS, double-apply tested live), and verifies the
expected table set. Applied to live CH: verify all 14 present.
