Localization bugfixes in config devices/entities/helpers

[karwosts]

Proposed change

Fix two issues in config data tables:

1.

Occasionally on refresh devices and entities table render without header labels:

There was a race condition where the columns were being memoized with the initial dummy localization function, and never refreshed when hass.localize updated. This adds the function pointer to the memoize function.

2.

The integration column in Entities table, and the type column in Helpers table, were applying sort/filter on the backend integration name, but displaying the pretty/translated name, which makes the sort and filter behave unexpectedly.

For example, you can have helpers which have the type "Combine the state of several entities". If you search for "combine", you will have no results, because the row is actually comparing against min_max, which no one would ever guess to type. Also it makes "Combine" sort alphabetically after "M" which is unexpected. Similar problems with Dropdown, Riemann, Toggle, etc.

This changes the table logic to sort and filter on the displayed text, not the pre-translation value.
