docs(token-swap/quasar): drop redundant 'Accounts for X' doc-comments

The opening line of each instruction's account-struct doc-comment was
paraphrasing the struct name (e.g. "Accounts for sweeping the admin's
trading-fee claim" above `ClaimAdminFeesAccounts`). Dropped those lines
and kept only the substantive notes (auth model, mut rationale, seed
quirks).

Also fixed a stray literal \u2014 sequence in create_config.rs that
should have been an em-dash.
