feat: unify build metadata and update deviceDisplayName for Tauri builds

[hazre]

Description

• Added 2 build time environment variables SABLE_PRODUCT_NAME and SABLE_BUILD_FLAVOR which basically replace all hard coded and duplicated references to "sable" and nightly/dev checks.
• Sable client can be renamed now in config.json with productName.
• Updated deviceDisplayName for Devices Tab in settings to handle Tauri desktop and mobile builds better. New format is
  Sable [FormFactor] [Variant] on [Browser] for [OS] and Sable [FormFactor] [Variant] on [OS].
• Combined cloudflare-web-deploy.yml and cloudflare-web-dev.yml into a single cloudflare-web.yml workflow using GitHub environments.

Some changes are required on the Github repo, which is to migrate (probably should keep old ones until this is merged) these secrets below to environments now:

TF_HTTP_ADDRESS
TF_HTTP_LOCK_ADDRESS

VITE_SENTRY_DSN
SENTRY_AUTH_TOKEN

@7w1 this is good to go, just requires adding the environment secrets, that's why ci is failing.
