Apply transforms, enabled state, and auth to hashed tool lookups (#5415)
FastMCPApp UIs call backend tools by a hashed name (`<hash>_<local_name>`) that survives renames, namespaces and proxies. This change makes those calls resolve through the same public `get_tool` lookup as a call by name, at every layer of composition. Transforms, `get_tool` overrides, session transforms, enabled filtering (including the fallback past a disabled highest version), version filters and auth now behave identically for both kinds of call. A hashed name resolves to the tool it identifies.

Renames from namespaces, `ToolTransform` and `mount(tool_names=...)` still resolve. Tool search and code mode, which replace the tool listing but pass name lookups through, still reach app tools by hash. The apps architecture docs describe the lookup.
