Improve table column and tag interactions

[ejsmith]

Summary

• remove redundant checkboxes from the column picker and make each row the add/remove target
• add optional Project columns to event and stack tables
• add optional compact Tags columns to event and global stack tables that show two tags plus a remaining count, with the hidden tags available in a theme-aligned hover surface
• use one neutral, bordered, clickable tag treatment across event and stack tables/details; clicking filters and the redundant per-tag filter icons are removed
• keep filter/copy guidance on individual tag tooltips while the overflow tooltip displays only the hidden tags
• align semantic log-level badges with the same compact tag shape, reduce their width, and use restrained 15% color-tinted backgrounds with 1px outlines in dark theme
• decode JSON-encoded exception extended data before rendering Additional Data so fields are not split into character rows
• include project names and tags in event and stack summary responses using cached bulk project lookups
• allow Project and Tags column state to be persisted in event, stack, and stream saved views

Verification

• npm run validate
• focused shared tag-list and log-level Vitest coverage (8 tests passed)
• focused exception Additional Data coverage for encoded, structured, and malformed extended data
• local synthetic COMException Playwright coverage confirms ErrorCode and ObjectName render as structured rows
• local Playwright dogfood coverage for event and stack Tags picker/table flows, the tags-only overflow tooltip, and matching event/stack tag presentation in light and dark themes
• saved-view Playwright coverage, including save/rename/reset/delete and switching views
• focused saved-view API coverage, including stack Tags persistence (6 tests passed)
• focused stack summary API coverage confirms tags are returned
• npm run build
• dotnet test -- --filter-class Exceptionless.Tests.Api.Endpoints.EventEndpointTests (103 passed)
• OpenApiSnapshotTests and SummaryDataTests (16 passed)

Breaking changes

None. The response additions are backward compatible, and the new columns are hidden by default.
