v3.0.19 Bug Fixes (#992)

* fix(mcp): replace relative oauth constent redirect by absolute redirect derived from APP_URL (#987)

* feat(journey): convert HEIC/HEIF uploads to JPEG for cross-platform compatibility

HEIC is an Apple-only format not recognised as an image by many browsers
and platforms. heic-to (lazy-loaded) now converts HEIC/HEIF files to JPEG
before upload in both the gallery and entry editor photo pickers.
Embedded metadata (EXIF, GPS) may be lost during conversion — documented
in the Journey Journal wiki page.

* fix(journey): skip heic-to import for non-HEIC files to avoid test env failures

* fix(notifications): prevent double-escaping HTML in password reset emails

buildPasswordResetHtml passed a pre-built HTML block to buildEmailHtml,
which then escaped it again — rendering raw tags as plain text in the email.
