Replace plain fmt.Sprintf confirmation prompt with a structured template using cmdio.RenderWithTemplate. The warning now uses color and bold formatting to clearly highlight the profile name, config path, and consequences before prompting for confirmation.

Resolve config path from the profiler instead of hardcoding fallbacks. Delete the profile before clearing the token cache so a config write failure does not leave tokens removed. Fix token cleanup for account and unified profiles by computing the correct OIDC cache key (host/oidc/accounts/<account_id>). Drop the nil profiler guard, add a success message on logout, and extract backupConfigFile in ops.go to remove duplication. Consolidate token cleanup tests into a table-driven test covering shared hosts, unique hosts, account, and unified profiles.

Merge shared-host token deletion verification into one main parametrized test by addding the hostBasedKey and isSharedKey parameters to each case. This replaces the TestLogoutTokenCacheCleanup test with an assertion: host-based keys are preserved when another profile shares the same host, and deleted otherwise.

Rewrite the test to use inline config seeds and explicit expected state. Add cases for deleting the last non-default profile, deleting a unified host profile with multiple keys, and deleting the DEFAULT section.

- Use profiler.GetPath() to resolve config path instead of hardcoding platform-specific defaults for the help text.
- Read DATABRICKS_CONFIG_FILE via env.Get(ctx, ...) instead of os.Getenv to respect context-level env overrides.
- Add abort message when user declines the confirmation prompt.
- Guard DeleteProfile against non-existent profiles to avoid creating unnecessary backup files.
- Add TestDeleteProfile_NotFound for the error path.

When --profile is not specified in an interactive terminal, show a
searchable prompt listing all configured profiles. Profiles are sorted
alphabetically and displayed with their host or account ID. The picker
supports fuzzy search by name, host, or account ID.

Document the four interaction modes (explicit profile, interactive
picker, non-interactive error, and --force) in the command's long
help text.

Four places built nearly identical promptui.Select prompts for
interactive profile selection (auth logout, auth token, root auth,
root bundle). Extract a reusable profile.SelectProfile function that
takes a declarative SelectConfig with label, profiles, and template
strings.

Also: add AccountID to Profiles.SearchCaseInsensitive so all pickers
support searching by account ID, and remove the redundant
not-found guard in DeleteProfile (ini.DeleteSection is already a
no-op for missing sections).

Extract writeConfigFile helper to consolidate the repeated
default-comment, backup, and save sequence shared by SaveToProfile
and DeleteProfile.

Also switch auth login from os.Getenv to env.Get(ctx, ...) for
DATABRICKS_CONFIG_FILE so it respects context-level env overrides,
consistent with the rest of the codebase.
