Fix the decompiler text-view context-menu ordering

The right-click menu in the decompiled code read in a near-random order. The
shared entry registry orders entries by a single Order value and only uses
Category to place separators, so a few defects scrambled the result: the
"Decompile" reference entry had Order=10, jumping above Copy/Select all; the
"Decompile to new panel" entry sat in a misspelt "Navigate" category (vs the
"Navigation" the other entries use), adding a stray separator; and it tied
Copy at Order 100 while "Go to token" tied Analyze at 200, interleaving
categories on the discovery-order tiebreak.

Pull the three navigation entries into a contiguous 150-170 band so they form
one block between the Editor (100s) and Analyze (200s) bands, fixing the
spelling so they share a category. No provider change: the existing by-hundreds
category layout is left intact, so the tree / search / metadata menus that share
the registry stay coherent.
