[No QA] Docs updates for E/A#96228 Reflect single-screen manual expense creation flow

[MelvinBot]

Explanation of Change

#96228 removes the newManualExpenseFlow beta and makes the new manual expense flow the default for all users. In the new flow, creating a manual cash expense is a single-screen inline form — the amount, merchant, and date are entered directly on the confirmation screen rather than through a separate "enter amount → Next" step.

This updates the How to manually create a cash expense steps in Create an Expense to match the current UI:

• Fixed the menu label casing: Create Expense → Create expense (verified against the live UI).
• Replaced the "Enter the amount and currency, then click Next" step with the single-screen Manual tab entry (amount, merchant, and other details entered inline before clicking Create expense).

Verified against the live UI

• The ➕ Create menu item is Create expense (lowercase "e").
• The create screen shows Manual and Scan tabs.
• The Manual tab opens directly to one inline form (Amount, Merchant, Description, Category, Date, Reimbursable, Report) with a Create expense button — there is no separate amount keypad + Next step.

Not changed (needs reviewer confirmation)

The SmartScan section was left as-is. #96228 also relates to showing Merchant, Amount, and Date fields on the Scan confirmation screen (#93854), but the Scan confirmation screen requires uploading a receipt, which couldn't be verified in headless web testing. If the Scan tab now reveals those fields (e.g. via a "Show more" control), the SmartScan section may also need a small update — please confirm.
