fix(feed): print weapons by name, not "ak47u entity"

The bridge names a kill's weapon by the held entity's short prefab name
(ak47u.entity), and the feed printed it with the dots turned to spaces:
"with ak47u entity". Every event read now gives the frame a weaponName
(server/model/titles/weaponNames.js): the game's own English name for the
53 ranged weapons (guns, bows, crossbows, launchers, flamethrowers), read
off the Oxide rig's item list on Rust 26139947, and for anything else the
prefab name as words with its .entity/.weapon ending dropped.

The site prints weaponName and falls back to the same stripping for an
older server. The prefab name stays in the frame: the title lists count by
it. Added at read, so stored rows are renamed too. No protocol change; the
events route's Swagger description names the new field.
