fix: Bugbot findings from promotion PR #396

[shujaatTracebloc]

Resolves the Cursor Bugbot finding surfaced on the data-ingestors promotion PR (#396, develop → master).

Fixes:

• Validator log labels drop suffix — normalize the label at the log site (append "Validator" only when not already present), so validator names that don't end in "Validator" keep the suffix. (Release develop → master #396 (comment))

Lands on develop; the promotion PR head picks it up on the next sync and Bugbot re-reviews.

Note

Low Risk
Logging and user-facing validation messages only; no change to validation logic or ingestion behavior.

Overview
Validator preflight messaging now uses a shared _validator_label() helper so every run/fail/warning line shows a consistent human-readable name.

Validator .name values were mixed: some already end in "Validator" (e.g. Data Validator) and many do not (e.g. Ingestable Records, Text Content). The previous success path assumed names were already suffixed and stopped appending "Validator", which dropped the word for unsuffixed names while still risking doubled text for suffixed ones. validate_data now normalizes once per validator and uses that label for running, failure, warning, success, and exception messages—appending "Validator" only when missing (case-insensitive), with whitespace stripped first.

Tests cover _validator_label cases and integration checks on success/failure output.
