docs(memory/typed-network): expand W/E/O/S abbreviation to full bank names

Test description and schema TSDoc both used W/E/O/S which is the
Hindsight paper §2.2 notation (𝒲/ℬ/𝒪/𝒮 with script-S for Observation)
but ambiguous in plain text since two banks start with O. Use the full
enum values in both places for self-explaining docs.
