feat: support storage policy in table details and create matview quick action

[emrberk]

Two related changes around retention on Enterprise.

Matview generator: Create materialized view on a table with STORAGE POLICY(...) was throwing an error. The generator now projects each clause into the matview's partition unit (DAY → DAYS, MONTH → MONTHS, YEAR → YEARS), preserves the toParquet ≤ dropNative ≤ dropLocal ≤ dropRemote order, and ladder-bumps the terminal clause so the matview retention outlives the source. TTL is floored at the partition unit with the same logic.

Table details drawer: The drawer now surfaces storage policy:

• If the DDL has clauses, the Storage Policy section renders each clause as a label/value card.
• On Enterprise, the section is always rendered; with no policy it shows a gray "Not configured" placeholder (same icon/style as the WAL-disabled row).
• The TTL card only shows when actually configured (ttlValue !== 0).

Test plan

• Right-click a table with STORAGE POLICY(...) → Create materialized view → resulting DDL validates on Enterprise (months-based, monotonic).
• Open the schema drawer for a table on Enterprise:
  • with a storage policy → clause cards render;
  • without one → "Not configured" placeholder.
• OSS: no Storage Policy section unless the source DDL carries one.
• TTL card: visible only when the table actually has a TTL.
