[No QA] Docs updates for E/A#90791 document bank-account search filter operator

[MelvinBot]

Why

Expensify/App#90791 adds a new Bank account advanced filter (operator bank-account:) on the expense Search page. It lets users with multiple settlement bank accounts scope expense results to the bank account they were reimbursed from.

The help article Use Search Operators to Filter and Analyze exhaustively lists every expense search operator, so this new operator should be documented there to keep the reference complete.

What changed

• Added bank-account: to the How to filter expenses using search operators list, describing that it scopes expenses to the settlement bank account they were reimbursed from, that suggestions appear after the colon (shown as bank name + last four digits, e.g. Chase xx1234), and that it's available only when the user has at least one bank account.
• Added bank account filter to the article keywords for retrieval.

Verification against the live behavior / UI

• Operator syntax bank-account: confirmed in CONST.SEARCH.SYNTAX_FILTER_KEYS.BANK_ACCOUNT.
• Advanced-filter row label is Bank account (common.bankAccount).
• Picker/chip/autocomplete label format ${bankName} xx${last4} confirmed in getBankAccountSearchLabel.
• Filter is gated to the expense Search type and only renders when the user has at least one filterable bank account (isFilterableBankAccount).

Authoring was checked against docs/HELPSITE_NAMING_CONVENTIONS.md, docs/HELP_AUTHORING_GUIDELINES.md, and docs/TEMPLATE.md — the change is a single list addition within the existing single-workflow article, so headings and structure are unchanged.

HelpDot Documentation Review

Overall Assessment
This PR makes a small, well-targeted addition to Use-Search-Operators-to-Filter-and-Analyze.md, documenting the new bank-account: expense search operator introduced in E/A#90791. It adds one bullet to the existing operator list and appends bank account filter to the article keywords. No structural changes were made, which is appropriate for a single list addition within an existing single-workflow article.

Scores Summary

• Readability: 9/10 - The new bullet is clear, concise, and follows the exact format of the surrounding operator list (backtick-wrapped operator, en-dash, description, example). The example Chase xx1234 is concrete and helpful.
• AI Readiness: 9/10 - Adding bank account filter to keywords improves retrieval for real search intent. The description uses full, natural phrasing and the UI-exact operator syntax. internalScope is present and unchanged. No new headings were needed, so the heading hierarchy remains compliant.
• Style Compliance: 9/10 - Uses the exact operator syntax (bank-account:) verified against CONST.SEARCH.SYNTAX_FILTER_KEYS.BANK_ACCOUNT, and the label format bankName xx last4 matches getBankAccountSearchLabel. Consistent with naming and authoring conventions. No prohibited or vague navigation language introduced.

Key Findings

• The addition matches the established list pattern precisely (operator, en-dash separator, description, inline example) for good consistency.
• Keyword addition is scoped and relevant, aiding semantic retrieval without keyword stuffing.
• Minor nit: the advanced-filter UI row is labeled Bank account per the PR description; the article describes the operator but does not reference that exact bold UI label. Since this section documents operator syntax (not UI navigation), this is acceptable and not a blocker.
• The change stays strictly within the single-workflow scope of the article, with no scope creep or extra cross-links.

Recommendations

• No blocking changes required. The addition is compliant and ready.
• Optional: consider mirroring the fuller example style used by some other entries if a sample query would help, but the current example is sufficient.

Files Reviewed

• docs/articles/new-expensify/reports-and-expenses/Use-Search-Operators-to-Filter-and-Analyze.md - Approved. One operator bullet and one keyword added; format, terminology, and metadata all compliant.

Note: This is a summary review. The change is small enough that no separate inline comments were necessary.
