New HelpIcon component + a DocsNavProvider context (webapp/src/lib/docsNav.tsx)
let any component request "open Docs to section X", bumping a nonce each
time so a repeat click re-triggers even if Docs is already open to that
section. NavMenu forwards that request into DocsPanel as a `target` prop,
which expands the right accordion section, scrolls it into view, and
flashes it (a brief accent-tinted background/border, settling back after
1.2s) — verified visually with a live server + Playwright. Opening Docs via
the plain NavMenu button explicitly clears any pending target, so that path
is unchanged: no forced section, no flash.
Added a "?" icon to FilterBar, LogTimeline, LogPreview, Metrics, Dashboards,
and NavMenu's own Settings/Presets panels, plus new Docs sections for
Timeline, Log preview, Settings, and Presets (previously undocumented).

MetricPrimitiveKind::Duration/MetricPrimitive::Duration(i64 ms) is a
new primitive kind. On a metric's Value-role param (ticket 022), kind
Duration is special-cased in apply_metric_to_log: instead of parsing
the captured text, the value is derived as elapsed time since the
previous counter event with the same label set, using the ingestion
timestamp. That "previous event" lookup is tracked via a new
IndexKey::LastMetricEvent/DataValue::LastEventTimestamp bookkeeping
entry rather than Bucket.values itself, because a label set's first
occurrence has nothing to diff against and pushes no Bucket entry at
all (per spec: omit, don't emit a bogus zero) — but it still needs to
be recorded so the *next* occurrence has something to diff against.
Duration values compose with the existing bucket/PromQL surface
unchanged (coerce_to_f64, filter comparisons, histogram()/gauge()).
On any other param (Label-role metric param, or a standalone
ParamDeclaration), Duration kind instead parses captured text as a
literal i64 millisecond count, same as Number. Profile round-trip
(ProfileMetricPrimitiveKind) and the Metrics.tsx declaration form are
updated to match.

Every metric declaration is now explicitly documented and modeled as
a counter: a match is an occurrence/increment, optionally labeled.
The bucket representation (BucketValue { values: Vec<(Sequence,
Timestamp, MetricPrimitive)> }) already was this; what it lacked was
any way to capture a *value* distinct from the occurrence-count-of-1
marker. Adds RegexToMetricPrimitiveMatcher::role (ParamRole::Label,
the default, or ParamRole::Value — at most one per metric, enforced
at declare time) so a metric can designate one param's captured
number as its per-event value instead of a label.
promql.rs/engine.rs add two new PromQL-evaluable forms built on top
of that value, both consumed as regular PromqlSeriesDto series like
sum()/avg()/rate():
- histogram(metric_name[width]): buckets matching events' values into
fixed-width buckets, one series per bucket labeled `le`.
- gauge(metric_name): the most-recent value per label combination in
the queried range.
Existing raw counter queries (metrics with only Label-role params,
sum/avg/rate) are unchanged. Profile files saved before this ticket
still load (role defaults to Label via #[serde(default)]). Metrics.tsx
gains a label/value role picker per param, and the Docs panel explains
the model and the two derived query forms.

Replaces the Metrics ComingSoon placeholder with a form for declaring
metrics (name, message_match_regex, param matchers) and a list/detail
view of declared metrics whose bucket values refetch on selection or
active-range change (no continuous polling, since declare's backfill
already resolves synchronously with the POST).
