Add --jsonschema option to the validate CLI command

[Moferanoluwa]

Change Description

Fixes #1500. As noted in the issue by @roll:

It's not supported yet but I think it's a good idea something like:

frictionless validate table.csv --jsonschema <schema>

The mapper is already implemented so it will be a simple feature to add

This adds exactly that: a --jsonschema option on the validate console command that takes a path to a JSON Schema profile, runs it through the existing Schema.from_jsonschema() mapper, and uses the resulting Table Schema to validate the resource — mirroring how --schema already works, just with a JSON Schema source instead.

Testing/Review Recommendations

• Installed the package locally (editable install) and ran it end-to-end:
  • frictionless validate table.csv --jsonschema schema.json against a JSON Schema requiring an integer id, with one row containing a non-numeric id — correctly reported INVALID with a type-error on the right row/field, exit code 1.
  • Same file with all-valid rows — VALID, exit code 0.
  • Confirmed no regression on the existing no-schema and --schema-sync paths.
• Ran the full existing frictionless/console/commands/__spec__/test_validate.py suite: 25 passed, 4 skipped (pre-existing skips, unrelated) before my change; 26 passed, 4 skipped after adding test_console_validate_jsonschema_1500, which follows this file's existing pattern (compares CLI JSON output against calling validate() directly with the equivalent Python API).
• ruff format --check and ruff check pass on all changed files.
• Added data/jsonschema.json as a small fixture (matching data/table.csv's id/name columns) since the existing data/ecrin.json JSON Schema fixture requires a display_title field that doesn't apply here.

AI Usage

• Tool: Claude Code (Claude Sonnet)
• Type: Implementing the option, tracing how Resource.schema already accepts Union[Schema, str] (confirming a Schema object could be passed directly with no other changes needed), and adding a test.
• Scope: frictionless/console/common.py, frictionless/console/commands/validate.py, its test file, and one new small JSON fixture.
