fix: EmbedGoogleMap passes boolean className to MUI Box

[jimmyandrade]

Summary

Jest / React PropTypes warn during tests (and potentially in development) when rendering EmbedGoogleMap via LocationStep:

Warning: Failed prop type: Invalid prop `className` of type `boolean` supplied to `Styled(MuiBox)`, expected `string`.
    at StyledComponent (.../@material-ui/styles/styled/styled.js)
    at Iframe (.../muy/dist/index.cjs.js)
    at EmbedGoogleMap (.../muy/dist/index.cjs.js)
    at EmbedGoogleMap (src/containers/EmbedGoogleMap/index.js)
    at LocationStep (src/components/LocationStep/index.js)

Root cause

muy@1.1.0 Iframe sets:

className: variant === "cover" && classes.cover

When variant is not "cover", that expression is false, which Material-UI Box rejects.

Acceptance criteria

• No PropTypes warning about boolean className when rendering EmbedGoogleMap without variant="cover"
• Cover variant still applies cover styling when needed (ParkingExpansionPanel)
• Production code changes are covered by unit tests
• Existing LocationStep / EmbedGoogleMap tests stay green

Notes

Prefer fixing in src/containers/EmbedGoogleMap (local implementation or safe wrapper) rather than patching node_modules/muy.

Resolution

Fixed on branch fix/embed-google-map-classname-boolean by implementing EmbedGoogleMap locally with string-safe className resolution.

Shipped

Replaced the thin muy EmbedGoogleMap re-export with a local MUI Box/iframe implementation in src/containers/EmbedGoogleMap so className is always a string or omitted (never false from variant === "cover" && classes.cover).

Tests

• Added coverage for embed URL, no boolean-className PropTypes warning, cover variant, and string className forwarding.
• EmbedGoogleMap production code is at 100% statement/branch coverage in the related Jest run.
• LocationStep and ParkingExpansionPanel suites remain green.

Branch: fix/embed-google-map-classname-boolean

Upstream root-cause fix opened on muy: muy/muy#153 (issue muy/muy#152). Local EmbedGoogleMap workaround in #443 remains until a published muy release includes the clsx Iframe fix.
