Claude be7a7b7baf fix(composer): register composer_bp and close a second empty-block gap
composer_bp defined the whole Plugin Composer feature -- the /composer/
page and all its API routes -- but web_interface/app.py never imported or
registered it, so every composer URL 404'd in the running app (every
composer test builds its own minimal Flask app and registers the
blueprint directly, which is why this went unnoticed). Wire it up the
same way pages_v3/api_v3 are: import, set config_manager/plugin_manager/
plugins_dir/project_root, register_blueprint(url_prefix='/composer') --
matching the prefix composer.html and composer-app.js already hardcode.

Also closes the other still-open half of a CodeRabbit finding: manager.py.j2
already guards element types the template has no branch for, but a
dynamic_text element with binding.source other than 'config' hit the same
empty-if-block bug one level deeper (its own inner if produced nothing).
Added the same pass fallback.

Verified both against current code before fixing; the other 8 findings
from that review were already fixed in earlier commits on this branch.

ChuckBuildsandClaude Opus 5 732c7d1a30 fix(composer): an element the template cannot draw broke generation
Reproduced from the review comment. A `group` element carrying minWidth
generated:

    if width >= 64:  # breakpoint: 64px+ displays only
    # <nothing>

manager.py.j2 wraps each element in the breakpoint and blink blocks, but the
body comes from the per-type branches -- and a type with no branch contributes
nothing, so the wrapper opens a block with no statements. ast.parse then fails
and the caller is told only "Generated code has a syntax error: expected an
indented block ... line 49", naming a line of generated source they never see.

Two defences:

- _preprocess_elements drops types the template has no branch for, alongside
  the existing `section` skip. This is the root cause: those elements should
  never have reached the template.
- The branch chain ends in `{% else %}pass`, so a type added to the canvas
  before its drawing branch exists degrades to a no-op rather than a plugin
  that will not parse.

The review also cited dynamic_text with binding_source != 'config'. That one
does not reproduce -- the branch emits a draw_text regardless -- which is why
an earlier attempt to reproduce this found nothing.

_RENDERABLE_ELEMENT_TYPES has to stay in step with the template: a type listed
with no branch emits an empty block again, and a branch missing from the list
is silently dropped from every generated plugin. A test asserts the two sets
are equal rather than trusting them to be maintained together.

Tests: 12 new, covering group/unknown/section against breakpoint, blink and
both nested, plus the set-equality and fallback checks. 7 fail with both
defences reverted. 172 composer tests pass; full suite 3862 passed, the one
failure being test_install_lowmem (pre-existing, awaiting #492).
