Update .po files for v1.6.2 -> v1.7.1 strings

Sweeps every translatable string introduced or rewritten across the
review-00-plan Phase A-E commits and adds them to both .po files.

Replaced (Phase A — M6 warning rewrite):
* "This operation permanently deletes all media files that are not
  assigned to any media category and are not used as featured image,
  product gallery image, or attached to any post." -> the new long
  enumeration that lists what IS detected, including the v1.6.2 termmeta
  + customizer exclusions.
* "WARNING: This operation will permanently delete all unused
  uncategorized media files from the server. This action cannot be
  undone!" -> the new short "WARNING: This action cannot be undone."

Added — Phase A (M6 warning bullets, H4 ragged-row, M4 guard):
* Detection-is-heuristic intro + 4 bullets (content HTML, ACF/meta,
  downloadable files, "delete media that nothing I can detect is using").
* "Row %1$d: column count mismatch ... Row skipped."
* "Import too large to stage (%d rows) ..."

Added — Phase C (H5):
* "Invalid file"

Added — Phase D (M1 + M4 rework):
* "Failed to stage import data on disk (write error)."
* "CSV contains no data rows."
* "OK"
* "Row %d: %s"

Added — Phase E (L7, L1):
* "Warning: %d variations have a sale price greater than the new
  regular price (sale > regular). Review the variations and adjust the
  sale price."
* 6 JS-side i18n keys: selectBothCategories, moveNoProducts,
  importInitializing, importComplete, deletionSummary, importSummary.

Project-Id-Version header bumped to 1.7.1 in both files. References
updated to point at views/manipulations/tab-remove-unassigned.php (the
v1.6.0 partial) for the M6 strings instead of the old aggregated
views/manipulations.php.

The .mo file regeneration is handled separately by the maintainer.
