Minimize memory usage when querying `system.jemalloc_profile_text` in
collapsed format by streaming results in small blocks instead of
buffering up to 65K rows.

Remove duplicate `const queryId` declaration inside the `try` block of
`getQueryCollapsedProfile` that shadowed the outer one, causing a
"Cannot access 'queryId' before initialization" ReferenceError every
time the function was called.
Rename the function from `getQueryFlameGraphProfile` to
`getQueryCollapsedProfile` to better reflect what it does: it fetches
collapsed stack data and renders it as text with action buttons,
rather than generating the flame graph itself.

Change the Query Profiler's Flame Graph section to show the collapsed
profile data in a text box (matching the Global Profiler output style)
instead of directly generating and downloading an SVG. The button is
now "Get Profile" and the output card includes Copy All, Save,
Generate Flame Graph, and Close buttons.
Extract shared helper functions parameterized by result div ID to
deduplicate profile output code between Global and Query Profiler:
`getFullProfileText`, `copyProfileOutput`, `saveProfileOutput`,
`closeProfileOutput`, `showMoreProfileLines`,
`downloadFlameGraphFromProfile`, and `renderProfileOutputCard`.

- Add `SETTINGS allow_introspection_functions = 1` to the `flameGraph`
query so it works without requiring the setting globally.
- Handle `SYSTEM FLUSH LOGS` failure gracefully: show a warning instead
of aborting, since the user may lack privileges (e.g. readonly mode).
- Preserve the flush warning when no trace log data is found, so the
user knows the data may appear after a delay.
- Fix empty result detection: `min`/`max` return default values (0)
on empty sets, not empty strings.
- Darken light theme `--warning-color` for better readability.

Query `jemalloc.prof.thread_active_init` from `system.asynchronous_metrics`
instead of the config value from `system.server_settings` to reflect
whether profiling is truly active at the jemalloc level.

- Add URL, user, and password input fields to the header, matching
the pattern used in `dashboard.html`
- Extract `buildUrl` helper and shared `fetchOptions` to deduplicate
URL building across all fetch call sites
- Add `add_http_cors_header` and `enable_http_compression` to requests
- Add `Authorization: never` header to suppress browser auth popups
- Change profiling check to query `system.server_settings` for
`jemalloc_enable_global_profiler` instead of `system.asynchronous_metrics`
- Wrap initialization in `start()` function for compatibility with
dataplanectl credential injection

Rename `system.jemalloc_profile` to `system.jemalloc_profile_text` and
the corresponding settings (`jemalloc_profile_output_format`,
`jemalloc_profile_symbolize_with_inline`, `jemalloc_profile_collapsed_use_count`)
to their `jemalloc_profile_text_*` equivalents, following the server-side rename.
Also change the default auto-refresh interval from 10s to 60s.
