Description

Multiple locale bundles removed the Citation key deviates from generated key entry but did not add
the new replacement-parameter variant Citation key deviates from generated key %0 used by
CitationKeyDeviationChecker (and present in JabRef_en.properties). As a result, affected locales
will fall back to the English key/text (or show missing text), reducing localization completeness.

Code

jablib/src/main/resources/l10n/JabRef_de.properties[1890]

-Citation\ key\ deviates\ from\ generated\ key=Zitationsschlüssel weicht vom generierten Schlüssel ab

Evidence

CitationKeyDeviationChecker looks up the parameterized localization key `Citation key deviates
from generated key %0 (with the %0` placeholder), so each locale must define that exact key. The
English bundle defines Citation\ key\ deviates\ from\ generated\ key\ %0=..., and some locales
(e.g., French/Italian) include it, but the affected locales in this PR (e.g.,
German/Spanish/Japanese and others) no longer contain any Citation key deviates... entry in the
relevant section because the old non-parameterized key was deleted without adding the %0 key,
causing lookup failure and UI fallback to the raw English key/string.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Several translated `JabRef_<lang>.properties` files removed the old key `Citation key deviates from generated key` but do not include the new key `Citation key deviates from generated key %0` (which is what `CitationKeyDeviationChecker` requests and is present in English). This causes localized UIs to fall back to English (or fail to resolve the key) for that integrity message.

## Issue Context
- `CitationKeyDeviationChecker` calls `Localization.lang("Citation key deviates from generated key %0", generatedKey)`, so the **key** must include `... key %0`.
- `JabRef_en.properties` contains `Citation\ key\ deviates\ from\ generated\ key\ %0=...`.
- Only some locales (e.g., French/Italian) provide translations for the `%0` key; in the affected locales, the prior (non-parameterized) key was removed and there is currently no `Citation key deviates...` entry at all.
- For each affected locale, add a line like:
 `Citation\ key\ deviates\ from\ generated\ key\ %0=<localized text including %0>`
 (You can adapt the previously existing translation text and incorporate `%0` appropriately.)

Description

The PR introduces whitespace-only changes (blank lines) across many localization files, increasing
diff noise without changing translations. This makes reviews harder and conflicts with the
requirement to avoid formatting-only changes in unrelated areas.

Code

jablib/src/main/resources/l10n/JabRef_da.properties[1099]

+

Evidence

The modified localization files end with runs of empty lines, and the PR adds additional empty lines
(as shown by the diff hunks), constituting formatting-only changes across many files.

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Many `JabRef_<lang>.properties` files gain an extra blank line at the end (whitespace-only change), creating broad formatting-only diffs.

## Issue Context
These changes do not appear to modify any key/value translations and primarily add/remove empty lines.
