Test blocked checkout retries and custom overlay slots in Chromium

[markmur]

Exercise repeated blocked attempts followed by a successful popup, checking that retries do not emit a premature close event. Also cover merchants replacing both overlay slots and retrying from their custom content.

The browser fixture records blocked alongside the existing lifecycle events so these sequences can be asserted. This coverage depends on the public event added in #835 and is separate from the bundle refactor in #916.

Bundle and package size

Web bundle sizes cover shipped runtime JavaScript. Package sizes cover the full published archive, including any source maps, declarations, and documentation it contains.

Platform	Measurement	Compression	Base	Head	Delta
Web	JavaScript bundle	Uncompressed	35.4 KiB	35.4 KiB	0 B
Web	JavaScript bundle	gzip	10.6 KiB	10.6 KiB	0 B

Web package files (uncompressed)

These are uncompressed file sizes; they do not sum to the compressed package size above.

How sizes are measured

Measured from the PR base SHA and PR head SHA. Web bundle rows sum shipped .js, .mjs, and .cjs files under dist/, excluding source maps and declarations. The gzip bundle size sums files compressed individually with gzip -n -9. npm package sizes are gzip-compressed .tgz archives; Android AAR sizes are ZIP archives. Package sizes are not final app binary sizes.
