feat(container): support sorting by creation time

[woolsen]

What this PR does / why we need it?

The container list can only be sorted by name. Add a creation time column so containers can also be ordered by when they were created, without changing the default sort (name ascending).

Depends on #14140: the third click (cleared state) restores the default order only after that PR is merged.

Summary of your change

• Add a sortable "Created" column. It displays the existing createTime value and uses the backend createdAt order field directly through the column prop.
• Use the standard three-state cycle, starting with newest first: descending → ascending → cleared (default name ascending).

Verification

• npm run build:dev passes.
• Playwright run against the built frontend with mocked API responses:
  • click 1: request orderBy=createdAt, order=descending;
  • click 2: request orderBy=createdAt, order=ascending;
  • click 3: created indicator cleared and request returns to orderBy=name, order=ascending (with fix(container): reset sort to default when cleared #14140);
  • the cells display the existing createTime values.
• The repository has no component/Playwright test setup, so the harness is not committed.

Please indicate you've done the following:

• Made sure tests are passing and test coverage is added if needed.
• Made sure commit message follow the rule of Conventional Commits specification.
• Considered the docs impact and opened a new docs issue or PR with docs changes if needed.
