fix(dashboard): validate display types against all datasets

[betegon]

Fixes #535. Fixes #536. Supersedes the incorrect fixes in #570 (merged) and #571 (closed).

What was wrong

The CLI accepted any --display + --dataset combination and silently saved broken widgets. Three independent issues:

1. Column default too broad (Dashboard: Top Issues Table widget created with no columns #536, partially fixed in fix(dashboard): default issue dataset table columns to ["issue"] #570) — columns: ["issue"] was applied for all issue dataset display types, not just table. A --display line --dataset issue chart got wrong columns.

2. Issue display type validation (Dashboard: Big Number widget invalid for Issues dataset counts #535) — only table/area/line/bar are valid for the issue dataset but any display type was accepted.

3. No validation for any other dataset — --display table --dataset tracemetrics (not supported), --display table --dataset preprod-app-size (not supported), --display details --dataset logs (spans-only), all silently created broken widgets.

Source of truth

All constraints sourced from Sentry's frontend dataset configs at commit a42668e:

Dataset	Supported display types
issue	table, area, line, bar
spans	area, bar, big_number, categorical_bar, line, stacked_area, table, top_n, details, server_tree
error-events / transaction-like / metrics / logs / discover	area, bar, big_number, categorical_bar, line, stacked_area, table, top_n
tracemetrics	area, bar, big_number, categorical_bar, line
preprod-app-size	line

What this does

• Replaces ISSUE_DATASET_DISPLAY_TYPES with DATASET_SUPPORTED_DISPLAY_TYPES — a full map for all 9 widget types
• validateWidgetEnums does one lookup into the map instead of a hardcoded issue check
• Column default remains scoped to issue + table only

Test plan

All existing tests pass plus new coverage for:

• preprod-app-size + table → error; + line → ok
• tracemetrics + table → error
• spans + details → ok; logs + details → error
