OU-1389: restructure folders

[PeterYurkovich]

This PR looks to update the folder structure of the proposed monitoring-plugin monorepo setup: https://github.com/observability-ui/harness/pull/4/changes

This PR performs as minimal changes as possible to the actual files, and only looks to move the files and create the new folder structure. Further work to do things like split files, refactor to fit the new structure, ect. are left to future PRs.

This PR is independant of #1034 and they can be merged in either order

Summary by CodeRabbit

• Bug Fixes

  • Improved proxy startup validation to reject reserved ports that conflict with monitoring service ports.
  • Aligned proxy routing and handler behavior with the monitoring routing flow.

• Refactor

  • Consolidated backend/server and frontend module wiring to shared locations to standardize routing and component loading.

• Chores / Tests

  • Updated Cypress specs and helpers to use shared data-test constants.
  • Simplified web build/dev scripts and removed standalone e2e/standalone build assets/config.

Walkthrough

The PR renames the Go proxy package to monitoring and updates server wiring to use the new package. The web app reorganizes imports and module paths across shared, alerts, incidents, legacy dashboards, metrics, perses dashboards, targets, and Cypress code, plus updates package scripts and exposed modules.

Changes

Backend package rename

Layer / File(s)	Summary
Package and server updates cmd/plugin-backend.go, pkg/monitoring/proxy.go, pkg/monitoring/sanitize.go, pkg/server/server.go	Go package declarations change to monitoring, and server routing, validation, and proxy startup now use monitoring types, ports, and handler construction.

Frontend reorganization

Layer / File(s)	Summary
Build and exposed modules web/package.json, web/src/e2e-tests-app.tsx, web/src/e2e-tests-index.html, web/webpack.standalone.config.ts, web/src/components/ols-tool-ui/index.ts	Scripts change to ts-node-based build/start/dev commands, exposed module paths move to features and shared, and standalone e2e/webpack entrypoints are removed.
Shared module rewires web/src/shared/**/*	Shared components, hooks, contexts, store, utils, and console helpers update their internal import sources to the new shared and feature locations.
Alerts and incidents imports web/src/features/alerts/**/*, web/src/features/incidents/**/*	Alerts and incidents components, pages, and utilities repoint their imports to shared hooks, types, constants, and relocated helpers.
Legacy dashboards, metrics, and targets web/src/features/legacy-dashboards/**/*, web/src/features/metrics/**/*, web/src/features/targets/**/*	Legacy dashboards, metrics, and targets modules update import paths to the reorganized shared and feature modules.
Perses dashboards imports web/src/features/perses-dashboards/**/*	Perses dashboards components, hooks, pages, and helpers update import paths, and the perses hook adds a missing-project guard.
Cypress import updates web/cypress/**/*	Cypress component tests, support commands, and page objects switch data-test and feature imports to the new module locations.
