Fix: Languages ​​changed when opening a dispute

[Matobi98]

Fix: Dispute messages now respect each user's language

Problem

When users involved in a dispute had different bot languages configured, dispute-related messages were sent using the language of who triggered the action, instead of the language of each recipient.

This caused inconsistent behavior, for example:

• If Alice (EN) opened a dispute with Bob (FR), Bob received the message in English.
• If an admin (ES) took the dispute, both Alice and Bob received the message in Spanish.

Each user should always receive bot messages in their own configured language.

Summary by CodeRabbit

• Refactor
  • Dispute notifications now determine initiator/counterparty and deliver messages in each party’s preferred language, improving clarity for buyers and sellers.
• Chores
  • Minor public API adjustment for dispute initiation callers to supply order context when starting a dispute.

Walkthrough

Adds getDisputeParties to centralize resolution of initiator and counterparty users and their i18n contexts; updates beginDispute and disputeData to use this helper, adjusts beginDispute signature to include an order parameter, and localizes dispute messages per party language.

Changes

Cohort / File(s)	Summary
Dispute message logic & signature bot/modules/dispute/messages.ts	Adds getDisputeParties() helper that returns initiatorUser, counterPartyUser, and language contexts (buyerLanguage, sellerLanguage, counterpartyLanguage). Refactors beginDispute() and disputeData() to use the helper, localizes messages per party, and updates beginDispute signature to include order: IOrder. Also extends imports to include getUserI18nContext.

🐰 I hopped through lines of code today,
Found gaps and stitched the language way,
Parties named, translations clear,
Hopping messages far and near 🥕✨

LGTM ✅ Clean fix for #553. The core issue was that dispute messages to both parties used ctx.i18n (the initiator's language context) instead of each user's own language.

The getDisputeParties helper properly resolves i18n contexts per user via getUserI18nContext(). Messages to the counterparty and to buyer/seller in disputeData now use their respective language contexts.

One minor observation: getDisputeParties calls getUserI18nContext 3 times — once for buyer, once for seller, and once for counterParty. Since counterParty is always one of buyer/seller, the third call is redundant. Not a blocker, but could be simplified.

Good fix, resolves #553.
