docs: point HTTP examples at the multitenant gateway

[andinux]

Context

The HTTPS server moved off the per-node address (<project-id>.<hosted-zone>.sqlite.cloud) onto the multitenant gateway (<project-id>.<hosted-zone>.gateway.sqlite.cloud). The dashboard's Weblite and Edge Functions pages already point there — the docs still pointed at the node.

Changes

Gateway migration (26 endpoint URLs, 6 files)

• platform/weblite.mdx (19), create-database.mdx (2), write-data.mdx (1), multi-code-example.mdx (1), sqlite-ai/aisearch-documents.mdx (3), platform/access-tokens.mdx (2)
• New Base URL section on the Weblite page
• Fixed a broken host in the AI search example (myproject.cloud, missing .sqlite) and the vague <your-project-url> placeholder in the access tokens page

Weblite auth headers (22 curl examples)

• Authorization: Bearer sqlitecloud://<project>.sqlite.cloud:8860?apikey=<key> → Authorization: Bearer <your-api-key>

Node connection strings (85 occurrences)

• Added the missing <hosted-zone> segment
• Normalized five inconsistent filler host names (myproject, myhost, xxx, host, mynode, plus abcd1234.global1.qwerty) to a single myproject.myzone.sqlite.cloud

sqlitecloud:// connection strings still target the node on port 8860 — only the HTTPS endpoints move to the gateway.

Placeholder conventions

Context	Form
Placeholder examples	<your-project-id>.<your-hosted-zone>.gateway.sqlite.cloud
Sample written as working code	abcdef123k.g4.gateway.sqlite.cloud (one realistic host, in multi-code-example.mdx)
Concrete connection strings	myproject.myzone.sqlite.cloud (neutral zone, no real value)

Open question for the reviewer

Six whole-host placeholders were left untouched: {host}.sqlite.cloud (quick-start-cdn ×3, quick-start-gin ×2), {HOST}.sqlite.cloud (knex ×1), and {hostname} in the Swift/PHP/SQLAlchemy pages. They come with prose like "To get the host, see under your Project name {host}.sqlite.cloud". Whether they are wrong depends on what the dashboard renders under the project name: if it shows cdrehk1lik.g4, they are already correct; if it shows only the project id, both the token and that sentence need rewriting.

Verification

Two sweeps over the repo come back empty: no HTTPS URL points anywhere but the gateway, and no sqlitecloud:// connection string is missing a zone segment. ai.sqlite.cloudsync bundle identifiers were left untouched.

While verifying the upload examples in this PR against the staging gateway, I found that the endpoint returns success even when the location URL cannot be fetched, and silently creates an empty database.

Reproducer:

curl -X 'POST' 'https://<project>.<zone>.staging-gateway.sqlite.cloud/v2/weblite/local-test.sqlite' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"location": "file:///Users/me/Downloads/some.sqlite"}'

Response:

{"metadata":{"connectedMs":132,"executedMs":3,"elapsedMs":135}}

The database is created but is empty so:

• can we provide a local file to be uploaded?
• should POST /v2/weblite/{database} fail when it cannot fetch location?

Added these fixes:

3a33dae Closes the unterminated quote on the POST /v2/weblite/sql URL, which made the example fail to parse in bash.
5a78e8a Adds the missing line continuation after the Authorization header in six Weblite examples, so the request body is actually sent.
3fecc39 Fixes $<encoded_query> to $encoded_query in the GET example so the URL-encoded SQL reaches the query string.
7119e6d Rewrites the create-database upload example to send a JSON location URL, since the endpoint fetches the file itself and does not accept a file body.
accaf9b Adds an Authentication section to the Weblite page stating that either an API Key or an Access Token is accepted as the Bearer value.
95ccfc2 Changes the write-data example to send the {"sql": ..., "database": ...} JSON body the endpoint expects instead of raw SQL.
8b551e5 Switches the Weblite upload and replace-database examples from an octet-stream body to the JSON location form.
ab0c335 Removes the empty-body create-database API example, which returns 422, and points readers to the Dashboard or CREATE DATABASE.
576a185 Rewrites the Weblite overview list to match the gateway's real API groups, replacing the non-existent Files group with Tokens, Memory, and MCP, and fixes the "executing SQLiteCloudArrayType" wording.

7012d2c Changes the Knex quickstart template to @{HOST}:8860 so the full server hostname can be substituted without doubling the .sqlite.cloud suffix.

eb910bb Changes the CDN and Gin quickstart templates to {host}:8860 and tells readers to copy the full hostname from the dashboard instead of assembling it from the project name.
