Hand-rolls a minimal PromQL parser (src/promql.rs) for metric-name +
label-matcher selection, optional [range] selectors, and top-level
sum()/avg()/rate() wrapping, rather than pulling in a full PromQL parser
crate — the required subset is small and a hand-rolled parser stays fully
engine-independent (mirrors filter_parser.rs) with no unused-AST overhead.
Adds EngineQuery::Promql/EngineResponse::Promql (engine parses + evaluates
in place against the index, no copying) and GET /api/query, returning
Vec<PromqlSeriesDto> (labels + (timestamp_ms, f64) points) for charting,
with malformed queries surfaced as 400 + ErrorDto.

Extend GET /api/logs to derive each declared param's value per log line
(regex + capture group + kind, matching that line's text) and include it as
a params map on LogEntryDto, omitting entries that don't match rather than
sending nulls. Add GET /api/params (list_params, mirroring list_metrics) so
the frontend can discover currently-declared param names. In LogPreview, add
a column-picker popover backed by that list, with the selection persisted in
localStorage under `ottyl.logPreview.visibleParamColumns`.

Exposes param/metric declarations and derived bucket data over HTTP:
POST /api/params and POST /api/metrics validate and declare against the
engine, persisting into the active profile (if any) so declarations survive
a restart; GET /api/metrics lists declarations; GET /api/metrics/:name
queries bucket values with label, time-range, sequence, and limit filters.
Adds a new EngineQuery::BucketValues variant that layers this filtering on
top of ticket 003's bucket_values helper.

Wires up Settings.css_entries behind a small settings API: import raw CSS
content to a file stored alongside settings.json, link external CSS
paths/URLs by reference (never deletable/copied), list all entries, delete
imported entries, and serve back imported content. CSS storage logic lives
on Settings (import_css/link_css/remove_css/css_content) with api.rs
handlers staying thin, matching the existing engine-query pattern.

Adds IndexKey::MetricDeclaration handling: DeclareMetric/RemoveMetricDeclaration
engine messages and a MetricDeclarations query, mirroring the pattern from ticket
001's param declarations. Params are derived from inline named capture groups on
the metric's own regex for v1 (referencing existing ParamDeclarations is left for
a future ticket). Validates the regex and every RegexToMetricPrimitiveMatcher's
capture-group reference at declaration time, reporting all bad matchers at once.

Implements the ParamDeclaration slice of the primary index: DataValue::ParamDeclaration
holds a regex + named capture group + MetricPrimitiveKind, stored under
IndexKey::ParamDeclaration{name} between LogParamSplit and ParamMetricSplit.
EngineMessage gains DeclareParam (validates the regex compiles and the capture
group exists before storing, returning a clear error otherwise) and
RemoveParamDeclaration; EngineQuery gains ParamDeclarations to list them back out
as ParamDeclarationDto. No API wiring yet (separate ticket).
