fix: add biome overrides for embed-core to prevent auto-import of node:process (#27387)

* fix: use import.meta.env instead of process.env in embed.ts

Using import.meta.env is Vite's native way to handle environment variables
in browser bundles. This prevents biome from auto-adding 'import process
from node:process' which breaks the embed.js in browsers.

* fix: migrate remaining process.env to import.meta.env in embed.ts

Complete the migration started by @hariombalhara by also converting
process.env usages at lines 1681, 1682, and 1700 to import.meta.env.
Update env.d.ts to include EMBED_PUBLIC_EMBED_FINGER_PRINT,
EMBED_PUBLIC_EMBED_VERSION, and INTEGRATION_TEST_MODE types.

This ensures no process.env references remain in embed.ts, fully
preventing Biome from auto-adding import process from node:process.

* fix: add biome overrides for embed-core to prevent auto-import of node:process

Reverts import.meta.env back to process.env since API V2's tsconfig uses
module: commonjs which doesn't support import.meta. Instead, adds biome
overrides for embed-core to disable useNodejsImportProtocol, noProcessEnv,
and noProcessGlobal rules that were causing biome to auto-add
'import process from node:process' on save.
