[PXT-1344] pxt db logs and pxt service logs (#1593)

Adds two CLI verbs that read the logs of a hosted database and of a
hosted service, so a failed deploy or
an opaque 500 can be diagnosed from the command line:

  pxt db logs pxt://org:db
  pxt service logs pxt://org:db/services/NAME

Both take --since (30s, 10m, 1h, 2d; default 1h), --tail N (the newest N
lines in the window, default 200,
at most 10000), --include-health (keep the health probe lines, left out
by default) and --json.

On the wire this is a new GET_LOGS management operation with its request
and response models; the local
daemon forwards it to the control plane like the other hosted verbs. The
control plane side is in
pixeltable-cloud (PR to follow), which reads the records back from
CloudWatch. This PR also adds the
operation to the read-only set and gives it the longer timeout, since
the server waits on a log query.

Normalize kwarg order in FunctionCall deserialization (#1599)

When a FunctionCall is stored in postgres, the JSONB dict does not
preserve key order. As a result, the display_str() of a FunctionCall may
change after a DB round trip.

This fix restores the original order of kwargs on deserialization. In
particular, it provides a "quickfix" of PXT-1347. We may still want to
do a more nuanced expr comparison for `pxt diff`, but we can reevaluate
its priority now that the immediate bug is fixed.

In any case, we definitely want a normalized kwarg order for display
purposes (tbl.describe(), etc)

Docs overhaul for launch: TableModel first run, Cloud, and How it wor…

…ks (#1562)

## Summary
- Getting Started is Why, Quickstart, then How it works (`diff` /
`update` / `prune`). Use-case pages lead with a `TableModel` in
`app.py`.
- First run: `pxt service example` → `pxt schema update` → `pxt service
update` → POST a row. Notebooks and tests still use
`pxt.create_table()`.
- Cloud: create an API key in the dashboard, set `PIXELTABLE_API_KEY`,
then `pxt db update`, `pxt schema update`, and `pxt service update`
against `pxt://org:mydb`. `pxt db update` does not insert rows and does
not start app endpoints. `pxt service run` is local only.
- Self-hosting is five pages: which local process, HTTP serving,
infrastructure, operations, security.
- Starter kit is two apps: `uvx pixeltable-new myapp` (`agent`) or
`--video` (`videointel`).
- Hop-1 uses a small Card layout. Hosted capability file is
[skill.md](https://docs.pixeltable.com/skill.md). Install stays `npx
skills add pixeltable/pixeltable-skill` (2.7.4).
- 0.7.x: types are required unless `| None`; B-trees are not automatic;
`pxt secret` is documented; names match without regard to case.

## Test plan
- [ ] Quickstart: `pxt service example` → `pxt schema update` → `pxt
service update` → curl insert
- [ ] `uvx pixeltable-new myapp` applies as `agent`; `--video` applies
as `videointel`
- [ ] Cloud: API key from the dashboard, then `pxt db update` / `pxt
schema update` / `pxt service update` against `pxt://org:mydb`
- [ ] `/resources/ai-skills` opens the AI Skills page (no bounce to AI
coding agents)
- [ ] `/howto/deployment/monitoring` redirects to operations#monitoring

PXT-1339: broken module eviction logic (#1574)

[PXT-880] Add mixed-case schema objects to the test db dump (#1566)

Pixeltable identifiers are becoming case-insensitive, stored
case-folded, but the metadata converter
that folds them has nothing to fold.

Rename a directory, a component view, a table and its columns, and one
computed column per table, and
name one embedding index. Add a column that is dropped again, so that a
name survives only in a
historical schema version. Regenerate the version 55 dump.

Run TestVideo.test_basic with xfail on Windows (#1526)

The test will be run, but any outcome will be ignored. This should
enable us to debug it.

Dashboard - multi-catalog browsing, pipeline inspector, table detail (#…

…1494)

The dashboard can browse hosted catalogs alongside the local one; table
and pipeline views reworked. Two catalog bug fixes come along, both hit
while testing
against a real catalog.

Dashboard
- Add hosted catalogs (pxt://org:db) next to the local one; persisted in
the browser (lib/catalogs.ts), each tree loaded lazily on open
(CatalogTree)
- Search spans the local catalog plus every added catalog, returning
fully resolvable paths
- Table detail reworked: row count, iterator columns marked, computed
expressions wrap and expand
- Pipeline inspector and column flow diagram simplified; kind badges for
table/view/snapshot/iterator
- Directory responses missing entries repaired client-side with a
one-time warning (api/normalize.ts, unit-tested)

Daemon
- GET /api/dashboard/search takes repeated catalogs params
- GET /api/dashboard/tables/meta returns row_count
- Column metadata carries is_iterator_col

Catalog fixes
- A component view whose iterator can no longer be located crashed on
len(None) unless its outputs were persisted; such views now load with
their stored data
readable
- InvalidGeneratingFunction never set name, so get_metadata() and
describe() raised AttributeError
