Add Client Api generation (#17961)

## Add API client generation to SDK dev mode and refactor orchestrator
into step-based pipeline

### Why

The SDK dev mode lacked typed API client generation, forcing developers
to work without auto-generated GraphQL types when building applications.
Additionally, the orchestrator was a monolithic class that mixed watcher
management, token handling, and sync logic — making it difficult to
extend with new steps like client generation.

### How

- **Refactored the orchestrator** into a step-based pipeline with
dedicated classes: `CheckServer`, `EnsureValidTokens`,
`ResolveApplication`, `BuildManifest`, `UploadFiles`,
`GenerateApiClient`, `SyncApplication`, and `StartWatchers`. Each step
has typed input/output/status, managed by a new `OrchestratorState`
class.
- **Added `GenerateApiClientOrchestratorStep`** that detects
object/field schema changes and regenerates a typed GraphQL client (via
`@genql/cli`) into `node_modules/twenty-sdk/generated` for seamless
imports.
- **Replaced `checkApplicationExist`** with `findOneApplication` on both
server resolver and SDK API service, returning the entity data instead
of a boolean.
- **Added application token pair mutations**
(`generateApplicationToken`, `renewApplicationToken`) to the API
service, with the server now returning `ApplicationTokenPairDTO`
containing both access and refresh tokens.
- **Restructured the dev UI** into `dev/ui/components/` with dedicated
panel, section, and event log components.
- **Simplified `AppDevCommand`** from ~180 lines of watcher management
down to ~40 lines that delegate entirely to the orchestrator.
