fix(sqllab): Set explicit Content-Type headers to prevent HTTP 406 errors

Fixes #36072 where SQL Lab queries with WHERE clauses failed with
"Database error: Not acceptable" in Superset v4.1+.

Root cause: Flask 2.3+ (upgraded in v4.1.0) has stricter content
negotiation that could return HTTP 406 when Content-Type headers
aren't explicitly set, particularly with ENABLE_PROXY_FIX or certain
Accept header configurations.

Changes:
- Add explicit Content-Type headers to /api/v1/sqllab/execute/ and
  /api/v1/sqllab/results/ endpoints
- Improve error handling with try-except blocks for result fetching
  and JSON serialization
- Add targeted integration test for WHERE clause queries

The fix ensures Flask 2.3+ doesn't attempt content negotiation that
could fail, while maintaining backward compatibility.

+- Empty translations (examples):
+    - msgid "%(subtitle)s\nThis may be triggered by:\n %(issue)s" → msgstr "".
+    - Several other msgid entries have msgstr "" (scan for msgstr "" occurrences).
+- Fuzzy entries present (e.g. entries annotated "#, fuzzy") — these need review and removal of the fuzzy flag after correction.
+- Typo in a translation: msgid "This action will permanently delete the user." → msgstr contains "uduario." (should be "usuario.").
+
+Recommended next steps:
+- Fix header Language to "es".
+- Remove/fix duplicate msgids: consolidate into a single entry and keep the correct translation.
+- Fill in missing msgstr values (or mark as untranslated intentionally).
+- Review and resolve fuzzy entries, then remove the "fuzzy" flag.
+- Fix obvious typos (e.g., "uduario" → "usuario").
+
+If you want, I can produce a patch that:
+- updates header Language to "es",
+- removes duplicate entries by keeping the first translated occurrence,
+- lists all msgids with empty msgstr for you to translate,
+or show exact locations (line ranges) for each problem. Which would you prefer?
