[Woo POS][Cash & Receipts] Add optional receipt button and receipt sending state mock UI

[kidinov]

Closes: #13003

Description

The PR:

• adds receipt optional button (depends on FF and Woo version)
• the click on the button opens mock of the receipt sending screen

Testing information

As this largely WIP, the most important here is to validate the there is no regression/changes in the flow when receipts are not available.

To validate the case when it's available:

• Use debug
• Either modify WooPosIsReceiptSendingAvailable.WC_VERSION_SUPPORTS_SENDING_RECEIPTS_BY_EMAIL version to the one you have installed or use the Woo store with 9.5.0 version

• I have considered if this change warrants release notes and have added them to RELEASE-NOTES.txt if necessary. Use the "[Internal]" label for non-user-facing changes.

Reviewer (or Author, in the case of optional code reviews):

Please make sure these conditions are met before approving the PR, or request changes if the PR needs improvement:

• The PR is small and has a clear, single focus, or a valid explanation is provided in the description. If needed, please request to split it into smaller PRs.
• Ensure Adequate Unit Test Coverage: The changes are reasonably covered by unit tests or an explanation is provided in the PR description.
• Manual Testing: The author listed all the tests they ran, including smoke tests when needed (e.g., for refactorings). The reviewer confirmed that the PR works as expected on big (tablet) and small (phone) in case of UI changes, and no regressions are added.
