Redesign query/search: syntax highlighting, autocomplete, richer results

QueryEditor.svelte wraps CodeMirror 6, not a hand-rolled
textarea-plus-overlay highlighter -- autocomplete needs real
cursor-aware popup positioning a plain textarea can't give. language.ts
is a StreamLanguage tokenizer for the pipe grammar; its token() function
must return real @lezer/highlight tag names looked up by string
('controlKeyword', 'operatorKeyword', 'name.function' for tag+modifier
pairs) -- a custom Tag.define() looks plausible but silently highlights
nothing. completions.ts is context-aware: stage keywords after `|`,
stats functions after `stats`, field names elsewhere.

A two-way-binding race between the editor's updateListener and an
external-sync $effect could drop characters on rapid/bulk input --
fixed with a lastEmitted guard so the sync effect only reacts to
genuinely external value changes, not its own echoes.

ResultsTable gets sortable columns (a real <button> in the <th>, so
sorting is keyboard-operable for free), resizable columns
(pointer-drag, deliberately mouse-only -- the resize handle stays out
of the tab order, same as most apps treat column resize), and
expandable rows. The row-expand affordance was originally a bare `<tr
onclick>` with no keyboard equivalent at all; fixed with
tabindex/role="button"/aria-expanded and an Enter/Space handler.

AddToDashboardModal lets a query built on the Search page become a
saved panel without hand-copying the query string.

// Shared between the SQL query page and the free-text search page —
// both /api endpoints return the same {columns, rows} shape
// specifically so this component didn't need to exist twice.
// Phase 5: sortable columns (client-side -- the rows are already
// fetched, re-sorting them here doesn't need a round trip), resizable
// columns (a plain drag handle, not a dependency -- this is a small
// enough interaction to hand-roll), and expandable rows for full
// structured-field inspection (useful the moment a query has more
// columns than comfortably fit, or a Map(String,String) attributes
// column whose JSON got cut off).
