Merge get_managed_services/get_managed_timers into get_managed_units
with a type parameter, drop unnecessary seen array. Extract shared
_write_unit_files core from create_job and create_job_from_edit. Add
get_job_command helper to replace triple-sed command extraction (3
call sites). Deduplicate list-timers call in show_status. Replace
rg/grep pipe in list_logs with journalctl --grep. Remove redundant
-h pre-scan loop in main. Net -97 lines.

Notifications now use ExecStopPost (fires on success and failure) with
status-aware icons/messages instead of ExecStartPost (success only).
Desktop uses dialog-information/dialog-error, email uses sendmail.
Flags (i, e=addr) are persisted as # SYSTAB_FLAGS= comments in service
files and exposed in edit mode via ID:flags syntax. Edit mode validates
schedules before applying (re-edit loop like crontab -e). -S and -L
accept an optional job ID to filter to a single job. Extract trim()
helper to replace inline whitespace-stripping idiom.

Unit files are now named systab_<6-char-hex> (e.g., systab_a1b2c3),
so the ID is derived from the filename — no more SYSTAB_ID comments
in unit files, no id-to-jobname mappings in edit mode. Removes
generate_job_name, get_job_id, get_job_by_id, ensure_job_id.
