WC-6046 simplify preview onboarding

[podonnell-dev]

Fixes WC-6046.

Simplifying preview onboarding logic, which covers the printing of a suggest previews block based on the user's current wrangler configuration file or dashboard settings. Reduced our process to a few principles

• align binding types with API shape; the only real difference here is the treatment of d1.database_idvs d1.id (deprecated)
• redact user's binding and setting values by default in the suggested config
• only specify fields that should not be redacted (very few, currently: placement.mode and r2_buckets.jurisdiction)
• only exclude fields or nested fields from the suggested config

  • Additional testing not necessary because:
• Public documentation

assemblePreviewScriptSettings() only sends the tail consumer service name to the Preview API, so an environment copied into this generated snippet is silently ignored. Since it is redacted, this also blocks the user until they replace a value that cannot affect the Preview. Exclude it while deriving the suggested Preview configuration.

Suggested change

	tail_consumers: config.tail_consumers,
	tail_consumers: config.tail_consumers?.map(({ service }) => ({ service })),

generally a hidden field based on docs. silently omitted here is okay for now, but needs to be revisited
