* db: quote postgres connection parameters

The DSN was built by string concatenation, so a password containing a
space, quote or backslash truncated it or injected extra parameters.
Build it with libpq keyword/value quoting and keep the password out of
the startup log line.

* db: mark the DSN test fixture password as not a credential

gosec G101 flags the literal assigned to Pass in TestBuildPostgresDSN.
The value exists to exercise quoting of spaces, quotes and backslashes
and is not a secret.

* types, db: build the postgres DSN as a URL from PostgresConfig

Review feedback: move the DSN construction onto types.PostgresConfig as
DSN(), so the database layer calls cfg.Postgres.DSN() and logs
redacted.DSN(), and build it as a postgres:// URL with net/url instead
of hand-rolled libpq quoting. Unix socket directories travel as the
host query parameter; bare IPv6 literals are bracketed. Tests parse the
URL back and check each component rather than the encoded string.

* types: silence gosec on the whole DSN test fixtures

gosec reports G101 on the composite literal that holds a Pass value, not
on the Pass line itself, so the previous nolint did not cover it. Place
the directive before each fixture element.

* db: drop imports left unused by the merge with main

The merge of main reintroduced the slices and strconv imports in db.go,
but the postgres DSN is now built by PostgresConfig.DSN and nothing in
the file uses them, so the package failed to compile and every CI check
failed on typecheck.

Also link the CHANGELOG entry to the PR.

* db: restore tests and formatting lost in the rebase onto main

Resolving the rebase conflicts in db_test.go kept this branch's side and
dropped the credential tests main had added, including the
requireCredentialConstraints helper another test still calls, so the db
test package no longer compiled. Restore the file from main; this branch
does not change it.

The resolution also indented the package clause in db.go and removed the
blank line between the standard library and module imports.
