Raise Cooldown Manager Centered minimum version after upstream fix

[Nnoggie]

CooldownManagerCentered v5.2.15 has a profile export bug. RegisterFrameWithLEM adds the runtime-only editModeEnabled function directly to ns.DEFAULT_SETTINGS.profile.editMode[configKey], so profiles initialized or default-filled afterward can inherit the function and fail export with:

Unhandled type: function

The upstream fix should copy the defaults table before adding runtime callbacks:

local defaultTable = CopyTable(ns.DEFAULT_SETTINGS.profile.editMode[configKey] or {})

Once CMC publishes a fixed release, update oldestSupported in WagoUI_Libraries/LibAddonProfiles/modules/CooldownManagerCentered.lua from 4.2.1 to the first fixed version.
