80bc24ed33* resources: keep each template's compiled pattern on the template #5248 made the shared build_regex cache unbounded on the premise that its keys were server-defined. They are not: a proxy caches the template strings its backend sends, so a backend whose templates change grew the cache for the life of the process (25000 entries after 1000 list-and-read cycles, ~1.5MB per read with long non-ASCII literals). A ResourceTemplate now keeps its own compiled pattern, keyed on its uri_template so a model_copy with a new template rebuilds it, and the pattern is freed with the template. The shared cache is bounded again and only serves direct match_uri_template callers. The pattern is read from the private-attribute dict directly because pydantic's private-attribute access costs ~0.3us on a path every read walks.

A wrapper now takes the source template's compiled pattern. Reading _list_query_params straight from the private dict also bypassed a model_copy update of it and a subclass property, so it is read as an attribute again, only when the URI carries a query.
