Isaac Connor c4073c964c feat: encoder parameter templates with editor + REST API closes #4778 closes #4802 ...

Adds a curated, per-encoder parameter-template library to ZoneMinder:

- Monitor edit page: a new Template row above the EncoderParameters
  textarea offers per-encoder templates (Balanced / Archival / Low
  Power / Low CPU). Apply merges the template's params into the
  textarea, preserving user-only keys. Advisory lint flags option
  keys that aren't recognised for the selected encoder. Switching
  encoders offers a same-name template on the new encoder via a
  native confirm.

- Options page: a new Encoder Templates tab with full CRUD —
  list / edit / copy / delete — backed by a new CakePHP REST API
  at /api/encoder_templates.

- Storage: a new EncoderTemplates DB table seeded with 14 shipped
  defaults across libx264 / libx265 / h264_nvenc / hevc_nvenc /
  h264_vaapi / hevc_vaapi. The table is mutable; ZM upgrades do not
  re-seed user-edited rows.

- valid_keys (the lint allow-list) stays in PHP code as ffmpeg
  vocabulary, not user data.

- Default params explicitly include pix_fmt to avoid the yuvj420p
  HEVC HW-decode rejection issue we hit earlier.

No C++ change. The textarea content is parsed by the existing
av_dict_parse_string call in src/zm_videostore.cpp.

version.txt -> 1.39.6.
