TCS-10: Enforce import type via consistent-type-imports

[brettcutt-aligent]

Description of the proposed changes
Enforce import type for type-only imports across consuming projects by adding @typescript-eslint/consistent-type-imports to the shared base ESLint config.

• Type-only imports were previously written as regular imports → now flagged as errors and auto-fixed to import type { ... }.

  // Before
  import { Cart } from './types';
  let cart: Cart;
  
  // After
  import type { Cart } from './types';
  let cart: Cart;

• Mixed runtime/type imports were previously a single statement → now split into separate runtime and import type statements (fixStyle: 'separate-type-imports').

  // Before
  import { createCart, Cart } from './cart';
  const c: Cart = createCart();
  
  // After
  import { createCart } from './cart';
  import type { Cart } from './cart';
  const c: Cart = createCart();

• Inline import('...').Foo type annotations were previously permitted → now disallowed (disallowTypeAnnotations: true).

  // Before
  let handler: import('./types').Handler;
  function render(c: import('react').FC<Props>) {}
  
  // After
  import type { FC } from 'react';
  import type { Handler } from './types';
  let handler: Handler;
  function render(c: FC<Props>) {}

• The rule lives in its own config object scoped to **/*.{ts,tsx,js,jsx,mjs,cjs} so it doesn't load against non-JS/TS files (e.g. GraphQL virtual documents extracted by @graphql-eslint/parser), which lack the TS parser services this rule requires.
