Problem

• Review of fix(ai): harden Prompts.get_all against old servers and malformed rows posthog-python#942 found a regression that also shipped in @posthog/ai 8.11.0 with getAll (feat(ai): add prompts.getAll to fetch all prompts at a label #4903).
• An old server that ignores the label filter returns latest versions. When every prompt's label points at an earlier version, every row classifies as a moved label and is skipped, so getAll returns {} as a successful result. It should raise the server-compatibility error, like it does when a row lacks the label entirely.

Changes

• After validation, if the server returned rows but every one was skipped as moved, getAll throws the compatibility error instead of returning an empty object. A single moved row among resolved ones stays a skip with a warning.
• Same fix as posthog-python#942 commit 8d26eb1, which already shipped in posthog 7.53.0.

Suggested change

	`prompts.getAll` now throws the server-compatibility error when the server returned prompts but none resolve the requested label, instead of returning an empty result. This happens on PostHog servers without label support on the prompt list endpoint when every label points at an older version.
	Fix `prompts.getAll` returning an empty result when the server cannot resolve the requested label.

jsdocs should mention the method throws
ideally it should not throw at all but all the other methods do that already
