Adds a cluster configuration knob to defer cluster active logical version advance until explicit operator action via the admin API. Default `true` preserves existing behavior; setting to `false` enables the new manual-finalization flow, which is gated by an Enterprise license via the `enterprise<>` property wrapper. Independent of `features_auto_enable`, which separately governs per-feature auto-activation after the version advance. The gating logic that consumes this property lands in a follow-up commit. The configuration option is made a non-user-visible tunable in 25.3.x because it is a noop until 26.2 but we want users to still be able to set it prior to starting a multi-verison-hop upgrade sequence. In 26.1 it is a normal, user-visible configuration option. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

@pgellert i made the option a tunable instead of a user-visible config in 25.3 since it's a noop in the 25.3->26.1 hop but still useful to be able to set prior to a multi-hop upgrade sequence. In 26.1 its normal user visiblilty. |

Manual backport of commit 90cfd44 from PR #30324, scoped to just the
features_auto_finalizationcluster configuration option.Backporting only the configuration knob (not the gating logic that
consumes it) lets operators on earlier releases set
features_auto_finalization=falsebefore upgrading to v26.2, wherethe manual-finalization flow ships. Without this backport, customers
would have to upgrade to v26.2 first and would lose the ability to
defer the active version advance before reaching the new minor.
Note that customers must be running this minor (or later) before the
major upgrade to v26.2 in order to make use of the manual
finalization flow.
Tracked in CORE-16305.
Original PR: #30324.
