feat: Drop blessed versions from a few components

[Bownairo]

ReplicaVersionRecords and the blessed versions list are updated in sync, as we no longer require an extra proposal to have each version "blessed".

This updates a few tools with the change.

[github-actions]

This pull request changes code owned by the Governance team. Therefore, make sure that
you have considered the following (for Governance-owned code):

1. Update unreleased_changelog.md (if there are behavior changes, even if they are
   non-breaking).

2. Are there BREAKING changes?

3. Is a data migration needed?

4. Security review?

How to Satisfy This Automatic Review

1. Go to the bottom of the pull request page.

2. Look for where it says this bot is requesting changes.

3. Click the three dots to the right.

4. Select "Dismiss review".

5. In the text entry box, respond to each of the numbered items in the previous
   section, declare one of the following:

• Done.

• $REASON_WHY_NO_NEED. E.g. for unreleased_changelog.md, "No
  canister behavior changes.", or for item 2, "Existing APIs
  behave as before.".

Brief Guide to "Externally Visible" Changes

"Externally visible behavior change" is very often due to some NEW canister API.

Changes to EXISTING APIs are more likely to be "breaking".

If these changes are breaking, make sure that clients know how to migrate, how to
maintain their continuity of operations.

If your changes are behind a feature flag, then, do NOT add entrie(s) to
unreleased_changelog.md in this PR! But rather, add entrie(s) later, in the PR
that enables these changes in production.

Pull request overview

Updates recovery/replay tooling to align with the new “elected replica versions” workflow by removing explicit “bless” handling and renaming related flags/steps accordingly.

Changes:

• Renames CLI flags/params from “add-and-bless …” to “add …” in recovery tests and tooling.
• Removes ic-replay logic for fetching/updating BlessedReplicaVersions and the corresponding “bless” ingress mutation.
• Updates recovery step naming/wording to reflect “elect” terminology (with a few remaining user-facing strings to fix).

• User-facing prompts in this step still refer to “bless” even though the step/terminology has been renamed to “elect”. This is confusing for operators and contradicts the updated StepType name.

            StepType::ElectVersion => {
                if self.params.upgrade_version.is_none() {
                    self.params.upgrade_version =
                        read_optional(&self.logger, "Version to bless (and upgrade to): ");
                }
