journal: multi-select emotions and per-category writing templates

- Mood switches from a single enum column to a many-to-many
  JournalEntryMood table so an entry can carry several feelings at
  once; the vocabulary is trimmed to 9 named emotions (dropped the
  overlapping satisfaction scale) with unified noun-style labels.
- Categories can define a content_template that pre-fills the "new
  entry" textarea when selected (only if the user hasn't started
  typing), seeded with a Story/Feelings/Decisions/Insights/Actions
  reflection template on the default "일상" category.
- Fixes a real attribute-injection bug found while building the
  template feature: Jinja's built-in |tojson filter doesn't escape
  double quotes, which breaks a double-quoted x-data="..." attribute
  when the JSON payload contains one; added |forceescape and a
  regression test.
