Alaister YoungandAlaister Young 46b31eb53a [FE-3379] feat(studio): warn when db passwords need percent-encoding (#47564)
Users who set a database password with special characters (\`@\`, \`#\`,
\`%\`, \`+\`, etc.) get no warning that it must be percent-encoded when
used in a connection URL, which leads to confusing connection failures
([FE-3379](https://linear.app/supabase/issue/FE-3379)).

**Changed:**
- `PasswordStrengthBar` now shows a warning-colored callout (with a docs
link) whenever the entered password contains characters that need
percent-encoding — this covers project creation, reset database
password, restore-to-new-project, and the Vercel deploy-button flow
- Replaced `DATABASE_PASSWORD_REGEX` (only caught `@`, `:`, `/`) with a
`passwordNeedsPercentEncoding()` helper based on `encodeURIComponent`,
so `#`, `%`, `+`, `?`, `&`, spaces etc. are caught too
- Moved `SpecialSymbolsCallout` from `ProjectCreation/` to
`components/ui/` since it's now shared

**Added:**
- Info admonition in the Connect sheet next to connection strings that
still contain `[YOUR-PASSWORD]` (direct connection + `.env`-based file
setups; hidden for psql and .NET where percent-encoding doesn't apply,
and after a password reset since the substituted password is already
encoded)

## To test

- Project creation → type a password containing \`#\` or \`@\` → warning
callout appears above the strength bar; disappears for alphanumeric
passwords
- Database Settings → Reset database password → same behaviour
- Connect sheet → Direct connection → note shows under the connection
string for URI/JDBC types, not for psql; after resetting the password
from the sheet, the note disappears (password is substituted already
encoded)
- Connect sheet → Node.js/Python/Go/SQLAlchemy file setups show the
note; .NET does not
- \`pnpm vitest run lib/password-strength.test.ts\` passes

## Summary by CodeRabbit

* **New Features**
* Added a dedicated password encoding note (with documentation link) on
direct connection screens when the password is embedded in a URL.
* Added an encoding hint to the password strength area when
percent-encoding is required.
* **Bug Fixes**
* Removed regex-based “invalid password” callout and replaced it with
safer percent-encoding detection logic.
* **Tests**
  * Added test coverage for `passwordNeedsPercentEncoding`.
  * Removed obsolete Project Creation password regex tests.
