Fix operation error flash showing function source code instead of translated message

[Copilot]

When a disabled operation is triggered (e.g. merging incompatible features), the flash notification at the bottom of the map displayed raw JS source code instead of the localized error string.

Root cause: operation.tooltip (function reference) was passed to .label() instead of operation.tooltip() (its return value). flash.label() stores the value as _label and renders it via .html(utilSanitizeHTML(_label)) — when _label is a function, JS coerces it to its source via .toString().

// Before — passes function reference, renders as source code
.label(operation.tooltip)()

// After — calls the function, renders the translated string
.label(operation.tooltip())()

• modules/modes/SelectOsmMode.js — click-triggered operations in OSM select mode
