Add wiki instructions path hierarchy walk-up

When looking up wiki docs for a screen, now walks up the path hierarchy
to find the most specific match. For example, for path
'Catalog/Product/EditProduct/Assocs', it tries:

1. Catalog/Product/EditProduct/Assocs (most specific)
2. Catalog/Product/EditProduct (inherits if no specific doc)
3. Catalog/Product
4. Catalog

This allows parent screen docs to apply to all child tabs/subscreens
unless overridden with more specific documentation.

Updated both getWikiInstructions (used by execute#ScreenAsMcpTool) and
loadWikiContent (used by moqui_browse_screens) to use this approach.
