feat(examples): apply 18-account buy upgrade to mint_and_buy + pumpswap

Browse Source 
Extends the 2026-04-28 program-upgrade prep (commit c25e2ed) to the
remaining trade scripts:
  mint_and_buy.py              — 18-account buy after bonding-curve-v2.
                                 Tested live with a fresh TEST mint (Solscan
                                 sig 62EZFCKVuxvqmzj...), succeeded.
  mint_and_buy_v2.py           — 18-account buy. Tested live with a
                                 mayhem-mode TEST2 token (Token-2022 + 5
                                 mayhem accounts), Solscan sig 44SvQSrhmHy...,
                                 succeeded.
  pumpswap/manual_buy_pumpswap.py / manual_sell_pumpswap.py
                               — Adds the 2 new pump-swap accounts (fee
                                 recipient + its quote-mint ATA) gated behind
                                 INCLUDE_BREAKING_FEE_ACCOUNTS = False; flip
                                 to True after 2026-04-28 16:00 UTC.
                                 Pre-existing program-side overflow at
                                 buy.rs:400 (AnchorError 6023) flagged in
                                 a comment — affects current pump-swap
                                 buys, unrelated to this upgrade.

Both pumpswap scripts now also accept TOKEN_MINT via argv[1].
