IDE schema browser: objects appear under the connected user

pgSaci keeps every user's objects in a shared PostgreSQL oracle schema. The
SYS.ALL_* / USER_* catalog facade was exposing that literally as owner
ORACLE, and sys.all_users never listed the login role — so DataGrip /
IntelliJ (which assume Oracle's "schema == user" model) showed no node for the
connected user and none of their tables.

• all_* / user_* facade views now report objects in the oracle schema as
  owned by current_user; user_* filters follow the same mapping.
• sys.all_users lists the connected user; the per-package schemas orafce
  creates (dbms_*, plv*, utl_file, plunit) are filtered out.
• PostgreSQL 18 catalogues NOT NULL as pg_constraint.contype = 'n' — mapped
  to Oracle constraint_type = 'C' with a NOT NULL <col> search condition
  instead of leaking the raw 'n'.
• dbms_metadata.get_ddl(type, name, schema): when schema is the connected
  user, resolve against the oracle schema.

Also in this line: CONNECT BY on NUMBER(p)-typed key columns (v0.0.3) —
the WITH RECURSIVE ancestor-path array had a typmod mismatch between the
union arms, breaking any hierarchy keyed on a precision-qualified NUMBER.
