chore: adopt shared Guiding Light configs and fix conformance gaps
Brings preauth from 18/34 to 30/34 conformance (auth-gateway profile). The
remaining four checks all depend on files this branch cannot change (see below).

PHP toolchain (§1)
  - require.php  >=8.4 -> ^8.5, and pin config.platform to 8.5.0. The old
    constraint also permitted PHP 9, which is not a promise we can keep.
    composer.lock regenerated with --lock: content-hash + platform-overrides
    only, zero dependency version movement.
  - friendsofphp/php-cs-fixer  * -> ^3.95. A wildcard meant CI was not
    reproducible.

PHPStan (§2.2)
  - vendor the shared phpstan.neon.dist (level 6) + a generated baseline.
    187 errors are captured rather than fixed; the baseline should only shrink
    from here.
  - add phpstan/phpstan:^2.1 to require-dev.

Code style (§8.2)
  - vendor the shared .php-cs-fixer.dist.php (@Symfony + @Symfony:risky +
    declare_strict_types) and apply it: 59 of 67 files reformatted.
  - Verified this is a formatting change, not a behaviour change: all 313 tests
    pass after the reformat, all in_array() calls already passed strict=true,
    and the remaining edits are @Symfony:risky idiom (yoda conditions, \count(),
    self:: over the class name).

Repository layout (§4.4)
  - docs/{Caddyfile,compose.yaml,example.env} -> docs/examples/, with
    example.env becoming the conventional .env.example. This is the layout
    GUIDING-LIGHT already cites preauth as doing correctly — it just needed
    renaming.
  - update the four readme.md references and a stale compose.yaml comment.
  - docs/v1.1-plan.md references are left alone deliberately: it is a historical
    plan recording what was done at the time, not live documentation.

Licence and security policy (§7)
  - add LICENSE (uniform MIT, matching composer.json).
  - add SECURITY.md describing the actual threat model: per-request
    allow/intercept, no caching of the login flow, app-set security headers,
    TOTP, and the fact that REMOTE_USER is trusted input.

Mobile accessibility (§3.3a)
  - templates/base.html.twig: drop maximum-scale=1 and add viewport-fit=cover.
    preauth was the one app already past the font-size precondition (controls
    render at 21.6px = 0.9em x 24px), so removing the lock is safe here and
    restores pinch-zoom for Android users.

Conformance tooling (§8.2)
  - vendor .ci/conformance.sh and .ci/css-control-size.py so the check runs
    from a checkout rather than fetching from the LAN-only private/ci.
  - .editorconfig synced from the version that keeps the Caddyfile tab rule.

Not included (blocked by the .gitea/workflows pre-receive hook):
  - ci-composer-audit, ci-composer-validate, ci-reusable-workflows.
    Workflow files may only change via a trusted ref, so the caller files are
    staged but not committed.

Also not included: dockerfile-nonroot (§6.4). Adding USER to an image with
VOLUME [/config, /data] changes volume ownership and needs an actual container
build/run to verify, so it goes in its own change.

# --- main options ---
# URI containing secret and config for TOTP, which determines the token to login
# app will generate one, if not provided, but you should copy it to your .env file
# format: "otpauth://totp/<label>?secret=<secret-key>"
#TOTP_URI='' # blank to have the app generate one at random
# how long will someone stay logged in, measured in seconds, zero for DEFAULT
#COOKIE_TTL=2592000 # default 30 days
# we can use a central auth, so that users only need to login once to have access to
# multiple services. Requires using sub-domains under the same domain.
# IE: if enabled have "service-one.example.com" redirect "auth.example.com", and after
# successful auth, user can visit "service-two.example.com" without having to login again.
#SUBDOMAIN_REDIRECT=false # default disabled, boolean
#AUTH_SUBDOMAIN='' # blank, hostname we send user to, to see login page
# --- extra options ---
# how long do we allow *ALL* traffic from an ip address after successful login
# could be useful if you have a system which does not handle cookies
#IP_TTL=0 # default disabled, time in seconds
# once blocked, do we respond with "I'm a teapot", false to use "Too many requests"
#TEAPOT=true # default enabled, boolean
# --- server / worker options ---
# (container/deployment only) restart each FrankenPHP worker thread after
# this many requests, containing memory growth across long uptime;
# matching the default from the old runtime/frankenphp-symfony package.
# 0 disables restarts. consumed by the Caddyfile, not the PHP app.
#MAX_REQUESTS=500 # default 500
# --- remote-user header ---
# Controls the value sent in the Remote-User header on successful auth.
# session: the session id (default, backward-compatible)
# static: a fixed string (set via REMOTE_USER_STATIC)
# mapped: look up session id in REMOTE_USER_MAP (format: id1:user1,id2:user2)
# none: do not send the Remote-User header at all
#REMOTE_USER=session
#REMOTE_USER_STATIC=authenticated
#REMOTE_USER_MAP=''

# Note: rate limiting can *NOT* be disabled, but you could allow hundreds of logins a second

# Comma-separated path patterns for public access. Wildcards:
# * matches any chars within one path segment (not crossing /)
# ** matches any chars including / (crosses path segments)
# Optional host prefix: host.example.com/path/**
# When empty (default), the feature is fully disabled.
