Fix substitute card badge rendering

[adrunkhuman]

Summary

• Walk cell HTML nodes directly instead of using goquery img[src*=...] selectors so card images are attributed to the player anchor that precedes them, not the cell as a whole.
• Introduce parsedPlayerCell to carry extra timeline events (cards for entrants) back to the caller without polluting PlayerLine.
• Add replacedYC/replacedByYC fields on lineupEntry and thread them into substitution note rendering so booked substitutes and the players they replaced show the badge inline.
• Drop the synthetic-entrant-for-badge-visibility path; the card is now visible directly on the exit/entry note of the real lineup row.

Test plan

• TestParseMatchPageSubstitutionCellAssignsCardsToBothPlayers — parser assigns YC to both starter and entrant in a shared cell.
• TestAnnotatedLineupKeepsBookedEntrantInReplacementNote — booked entrant no longer needs a synthetic row; badge appears on the starter's exit note.
• TestFormatLineupPlayerShowsBookedReplacementInsideHomeNote — home exit note renders (72' M. Rzuchowski■).
• TestFormatLineupPlayerShowsBookedReplacedPlayerInsideAwayNote — away entry note renders (for J. Kowalczyk ■ 46').
