feat(sub): add dynamic remark variables with Jalali date, transport, and status tokens (#5430)

* feat(sub): implement dynamic single-bracket remark variables with timezone-aware inline Jalali conversion

* Update .gitignore

* Update .gitignore

* merge: bring in origin/main commits to resolve conflict base

* fix(sub): address review issues in dynamic remark variables

- Add TIME_LEFT to unlimitedDropTokens so segments containing only
  {TIME_LEFT} are dropped for unlimited clients (same as DAYS_LEFT)
- Remove dead uiSingleBraceRe variable (translateUISingleBrackets uses
  a character scanner, not this regex)
- Change expireDateLabel to use time.Local instead of UTC, consistent
  with jalaliExpireDateLabel
