HOTFIX: add #18/#13 schema to Postgres (chat history returned empty)

Browse Source 
Production runs DB_BACKEND=pg, but the message_hidden table (#18) and
pinned_at/pinned_by columns (#13) were only added to the SQLite migrations in
db.js — never to schema.pg.sql. So thread/conversations/pinned queries hit a
missing relation/column and 500'd, which surfaced as "chat history removed"
(no data was ever deleted — the reads just errored).

pg.js init() runs schema.pg.sql on every boot. Added the message_hidden table
and, because CREATE TABLE IF NOT EXISTS can't add columns to the existing
messages table, idempotent ALTER TABLE ... ADD COLUMN IF NOT EXISTS for
pinned_at/pinned_by. Restores all chat history and re-enables pin + delete-for-me.
