New GET /api/dbstats reads VictoriaLogs /metrics (stored lines, size on
disk, raw size, free space, partitions, retention) and two LogsQL queries
(period covered, distinct hosts and apps, lines of the last 24 h and hour),
cached for 30 s. The danger zone shows them, sizes in KB/MB/GB or Ko/Mo/Go.

The presets move from app.js to presets.json, built into the binary and
served by /api/presets. PRESETS_FILE (default /data/presets.json) replaces
the list when present; it is read again each time Settings opens and the
built-in list is used if it is invalid. docs/presets.md (EN/FR) explains
each preset and the file format.

New source, off by default and switched in Settings > Sources, that
collects the system logs of the machine hosting the stack:
- reads the systemd journal files directly (pure Go reader, no
journalctl in the image), from /var/log/journal and /run/log/journal
mounted read-only under /host;
- falls back to following the text files of /var/log (syslog,
messages, *.log) on hosts without journald;
- positions saved in /data/hostlogs-state.json, HOST_LOGS_BACKFILL
read when the source is turned on;
- source_type "host", selectable in the Source filter;
- compose mounts and group_add (HOST_LOGS_GID, adm by default), docs.

The histogram above the list becomes a configurable timeline:
- Scale linear / sqrt (default) / log, height S/M/L, bars or area.
- Colors: stacked by severity (error+, warning, the rest), intensity
against the median of the window (calm, burst >3x, anomaly >10x), or
none; colors are CSS variables with light and dark values.
- Vertical graduations on round local times (hh:mm:ss, hh:mm, dd/mm).
- Tooltip: interval bounds, total and detail per severity.
- Division automatic (~100 intervals) or fixed (1 s to 1 day), capped at
300 intervals by the server; intervals aligned on the local time zone.
- Refresh off / 5 s / 15 s / 30 s / 1 min / at each new interval. In
live mode the last interval is incremented from the SSE stream and the
timeline reloads at each new interval; paused while the tab is hidden.
- Click a bar to zoom on its interval, drag to zoom on a selection: the
list, export and counters follow through new from/to parameters.
The timeline now runs on the server clock (bounds and "now" come from
/api/histogram): the axis was drawn from the browser clock and refreshed
every 30 s only, so a clock difference with the server or a hidden tab
left it behind the logs.
/api/histogram returns interval indexes with the count per severity; the
division logic lives in histogram.go with table-driven tests.

- SyslogServer opens and closes the UDP/TCP listeners at runtime from the
configuration saved in /data/syslog.json; a busy port no longer stops
Logstream, the error is shown in Settings instead.
- Sources tab: syslog section with an on/off switch, UDP and TCP labels,
the live listening state and the published port (SYSLOG_PORT, passed as
SYSLOG_PUBLIC_PORT for display; the mapping stays in docker-compose).

- docker.go follows every running container through the Docker API
(events + logs with follow), resumes after a restart from the last
position saved in /data/docker-state.json, reads DOCKER_BACKFILL (1h)
of history for new containers, strips terminal color codes and guesses
the severity from the line (JSON, logfmt, [ERROR], ERROR ...).
- Logs carry source_type=docker, container, container_id, image,
compose_project, compose_service and stream; host is the Docker host.
- Settings > Sources: one switch per container (grouped by compose
project), enable/disable all, follow new containers automatically.
Choices are saved per compose service in /data/docker.json.
- Source filter (syslog / docker) in the filter bar and the live view.
- docker-compose: read-only docker-socket-proxy; Logstream and the proxy
are labelled logstream.exclude=true and never collected.

- GET /api/export.csv streams every stored log matching the filters
(newest first, up to EXPORT_MAX rows, 100000 by default) straight from
VictoriaLogs, with dates in the time zone chosen in Settings.
- Export button with two variants: CSV (comma, UTF-8) and CSV for Excel
(semicolon + BOM, formula injection neutralized).
- Store.QueryStream streams query results without buffering them.
- Mobile: filter bar keeps two selects per row, count next to Export.

- Reverse DNS (cached PTR lookups): IP hosts are stored with their name
in 'host' and the IP in 'host_ip'; older IP-only logs are resolved on
display and the host filter shows 'name (IP)'. RDNS / DNS_SERVER env.
- Settings > Danger zone: delete all logs (type PURGE to confirm) through
VictoriaLogs /delete/run_task; -delete.enable added to docker-compose.
ALLOW_PURGE env to disable it.
- Remove the custom YYYY-MM-DD - HH:MM:SS:mmm format; default is now the
usual French display DD/MM/YYYY HH:MM:SS.
